#sims render tutorial

The tools I use most I've highlighted below:

I won't outline their uses just now, but we'll be going over them as we use them.

Different creators like to split their blender window up in different ways, but this is my preferred setup when I'm working:

I use the yellow half of the screen as a render preview/3D workspace

I use the blue half for shader editing, posing, etc.

You can set yours up like mine or find what's comfortable for you.

When you first open blender, you'll be greeted by the default cube, lamp, and camera.

Delete them! You can do this two ways:

Click and drag your mouse over all 3 and delete or Select all 3 in the side menu and hit x on your keyboard

Step 1: Importing our Sim

After deleting the default items, we'll import our sim. This tutorial assumes you've already ripped your sim (if you haven't, check here for how to do so!)

Now, let's import.

Click file -> import -> collada (dae) Select your DAE and click "import"

Your sim will look a little... off (thick eyelashes and a weird shine), but that's okay we're going to fix it! Your sim might also look solid white. If that's the case, make sure you're in the right mode. You can adjust modes by clicking on one of the four circles in the top right of the screen.

These are your viewport modes.

Wireframe (far left) - good for mesh editing Solid (middle left) - good for posing Material Preview (middle right) - what we work in most, shows everything with textures (color) Rendered (far right) - this shows your render preview We'll be working mostly in Material Preview

You can also switch between modes by hitting z on your keyboard then selecting which one you want I'll be using mostly keyboard shortcuts but I'll show you how to do both as we go along

Step 2: Adjusting Our Sim's Textures

Let's fix our sim's textures.

First. set up your workspace. Separate your workspace into two windows (as shown in the picture above with a yellow half and a blue half) and select "shader editor" in your right-side window. Like this:

Next, navigate to your Outliner and click the little dropdown beside "rig"

Under "rig" you'll see your sim's body parts listed. We're going to select "Body" When we click "Body", these colored blocks will appear in our shader editor window.

These are called Nodes. We use Nodes to adjust textures for various items in blender (sims, walls, furniture, etc). To add a new Node, you can select "add" in the top bar, or hit Shift+A on your keyboard and add in the node you need.

We're going to add in a Mix Shader and a Transparent Shader (both found under the Shader tab) and adjust our nodes this way:

Snug the Mix Shader between the Principled BSDF and the Material Output. Now we have to connect our Nodes and adjust our Principled BSDF. For the sake of this tutorial, I'll show the basic Node & Shader adjustments, but we'll go into each of them in a later tutorial.

Adjust your Principled BSDF like this, then connect your Node lines exactly like this:

You'll see that our SIm's body looks a bit different from her head, hair and shoes. That's good! Now we need to duplicate that texture to the rest of our sim.

Navigate to your Outliner again, and use Shift+Click to select the rest of the body parts in the list Don't select pose or rig.001 and make sure the Body is selected first EDIT: You'll only see "body" if your sim has a full body outfit on! If they have a shirt and pants, you'll have "Bottom" and "Top" instead! In this case, select "bottom"!

Now, hover your cursor over your sim/the 3D viewport window, and press Ctrl+L on your keyboard. This brings up the Link/Transfer data window. Select "Link Materials"

Our sim is looking better, but her eyelashes are still dark, let's fix that now.

In your Properties area, navigate to Material Properties (the little red ball)

Change your Blend Mode to Alpha Hashed We will always set Blend Mode to Alpha Hashed

Now our sim looks right!

Navigate to Render Properties and select "Cycles" in the Render Engine dropdown

If you have an older system, leave CPU selected If you have a newer or beefier computer, select GPU complete I render on a MacBook Pro, so I'll select GPU

Under Sampling -> Viewport, make sure you click on the Denoise, this will clean up our render preview so we can more easily see what the final result will look like

Under the same Sampling tab, adjust your Max Samples to match mine (32 in the viewport and 128 in the render window, this will speed up your render time)

Click into Output Properties and select "Render Region" and "Crop to Render Region", and change the frame rate to 50fps In the Output tab, change the Color Depth to 16 Nothing will change in our 3D Viewport, but the settings are ready to go

Step 2: Adding Lights

Right now, if we were to change our mode to Rendered, we'd have nothing but a black box. This is because our sim is in a cube with no light source Let's add some lights! For portraits, I like to use a combination of Spot and Point lights You add in lights the same way you add in the camera and the cube, either by clicking "Add" in the top menu or with Shift+A on your keyboard and selecting Light -> Spot or Point I'm going to add a Spotlight first I like to add in lights in Rendered view, but be careful using rendered view as it ups the chances that your Blender will crash

I added in a spotlight but it appears that nothing happened Objects are added into Blender at the Cursor point. I never adjusted mine so it's at the center of the axis, meaning below my sim's feet and outside of the box Using G and X,Y,Z, I'm going to move my spotlight up

Now the light is above her, but I want it shining on her, so I'm going to rotate it forward Rotate objects using the R key and X,Y,Z directions on your keyboard

That's not bad, but I want more dynamic light. I'm going to add two more spotlights for 3 point lighting

This is looking better, and you can see where my lights are and how they're oriented Now let's adjust the background Select your cube in the Outliner panel and navigate to Material Properties Click "new" in the bar Then navigate to your Shader Editor window and you'll see a Principled BSDF Node is here

We're not going to do anything too fancy here, just change the color of the cube and some aspects of how it looks Change the color of your box using the color wheel then adjust your nodes to everything is set to zero except roughness

You should have something like this (of course use whatever color compliments your sim best)

I don't want the background to be super flat, so I'm going to adjust the Metallic value on mine Now I have this:

I like the lighting but I think it might be a little too bright Let's adjust it a little In your Outliner panel, select one of the spotlights then go to "Object Data Properties" (the little lightbulb)

I'm going to adjust the Power to 5 and click off multiple importance and click on shadow caustics, like this:

Do the same for all three spotlights and you should have something like this:

That's better, but let's draw attention to her face with a Point light Add in a point light the same way as a spot (shift+A, light -> point) or Add in the top bar) and move it in front of her face

This is obviously way too bright, so let's adjust it like we did for the spotlights I've changed the radius and adjusted the power to 8, as shown here:

Here's the result:

That's much better! Normally at this point I would probably change her hair and add in jewelry and make minor adjustments to this and that, but for the sake of this super simple beginner render, we're ready to go! Before you run your render, save this file somewhere easy to find. I'll be using the same file for future tutorials!

Step 3: Rendering!

Once you've done all the setup, rendering is actually super easy Make sure you switch your 3D viewport back to Material Preview (rendering while in rendered mode has a tendency to make blender crash) Then go up to the navigation bar and select Render -> Render Image

A new window will pop up, and your render will begin!

Rendering time will depend on how complex your scene is and how many assets you've added in. Ours is very simple so mine says it'll take about 6 minutes

And it's done! Save your render and either post it or edit it in your favorite photo editor!

UPDATE 7/17/23

As you can see, my render was looking very glowy. I didn't know why (there was no glare node in the compositing settings or anything that would cause this, or so I thought), until I adjusted the roughness values on my sim.

Now it looks like this:

So if yours is looking glowy, adjust the roughness to 0, then back up to 10 and that should fix it!

Homework:

Your Render School homework is to create a simple portrait render using these tutorials and tag me in it! I can't wait to see what yall make!

Please leave any questions in the comments below or send an ask and I'll help as best I can!

Step 1: Exporting Poses for Blender

Before we can pose our sim in blender, we need to prepare the pose. I'll be using this pose set by @roselipaofficial for this render! Download your pose and open it in Sims 4 Studio. Click "Clips" at the top

For my render, I'm going to use Pose #3 When you select your pose, the Clip Name will change (Each creator names their poses differently) Before we export, make sure you're set to the right rig! Blender does terrifying things if you export to the wrong rig. I'm posing an Adult Female sim, so we're good to go! Export the pose and save it somewhere that's easy to find! Now let's go back to Blender

Step 2: Posing Our Sim

In Blender, click on "Pose" in your Outliner Then hover over your sim/3D viewport area and hit I on your keyboard (not L) to open the Keyframe menu Select "Location & Rotation"

In your right-side workspace, change your editor type (window) to Nonlinear Animation This is where we'll pose our sim!

You'll see rig and rigAction. Click the little dropdown arrow next to rigAction, then you'll see a highlighted orange track

Now let's add in our pose Click File -> Append and navigate to where you saved your pose Double click your pose file, then elect the "Action" folder Double-click the file that comes up under "Action," that's your pose

It'll appear as though nothing happened... but it did! In your Nonlinear Animation window, click "Add" and select "Add Action Strip" Make sure your rigAction line is highlighted orange like mine is!

Select the Roselipa pose we added from the list, and TA DA! Our sim is posed!

Step 3: Setting up our Scene

I always add in my camera before doing anything else, that way I can adjust as necessary based on what I want the final render to look like. To add in a camera, you can either select "Add" in the top bar of your 3D viewport window, or hit Shift+A on your keyboard and select "camera"

You'll see that a camera has been added to our Outliner, and we can see it in our 3D Viewport (If you still have a lamp in your Outliner like I do, go ahead and delete it now, we don't need it)

I personally like to move my camera around in real time so I know where it's going. To switch to camera view, click the little camera icon in the right toolbar of your 3D Viewport You'll see that our camera is in a weird spot, but that's ok we're going to fix it

I want a portrait, so I'm going to switch the resolution settings. To do this, go to Output Properties and change the resolution values. The default is 1920x1080, but I like higher resolution renders personally, so I'm changing mine to 2080x2920. Only go up in resolution if your computer can handle it!

Now let's move our camera I like to use the Axis directions on my keyboard to get the camera where I want it Select your camera in the Outliner, then hover your mouse over the 3D Viewport Using the "G" key (the shortcut for move), combine G and "X, Y, or Z" on your keyboard to move the camera where you want it This will be fiddly at first but you'll get better with practice! I've set my camera up like this:

For basic portrait renders, I like to just use lights and a simple cube Remember the default cube we deleted in the beginning, we're going to bring it back now Add it in the same way as the camera, either by selecting "Add" in the top menu and choosing Mesh -> Cube, or by pressing Shift+A on your keyboard and selecting Mesh -> Cube I use keyboard shortcuts, so I'll add mine with Shfit+A like so:

You'll probably have something like this, your sim floating in a box

Use the same method you did to move the camera ("G" plus axis directions (X,Y,Z) to move it up and use "S" on your keyboard to scale it up To scale up, hit "S" then move your mouse outward Then center the box over your sim We want to have something like this:

Click into Camera view (click the camera on the right) and you should have something like this:

In Part 3, we'll adjust our render settings, add lights, and render!

I'd wanted to include those in part two, but Tumblr is yelling at me about my photo limit.
