#multilut faq

Hi! The only thing I can think of is to check in whatever lut shader you’re using that the size of the lut is correctly specified.

Take a look inside my shaders and you’ll see it has a section for tile size, tile amount, and lut amount.

The lut amount means the number of luts you can switch between in the drop down menu. So for The Moods for example that’s 30, for Thatched it’s 15.

Tile size and tile amount refer to the physical proportions of each lut strip (and so these numbers will be the same no matter how many lut options you have in the drop down menu).

All my most recent luts have the same proportions, the tile size is 64 (that means each square of colour grading in the lut is 64px by 64px square), and the tile amount is 64 (that means there are 64 of those squares, which it turn means one lut strip would be 4096px long and 64px tall).

I’ve seen a few people now with crashing issues when using my most recent presets. Each time I’ve asked to look at their log file the last entry before the crash has been something like:

| INFO  | Resizing image data for texture 'V__texMultiLUT' from 1024x544 to 262144x69632 ...

Asking the user to delete MultiLUT.fx from their Shaders folder has fixed the crashing each time so far.

I recently switched to using Prod80′s LUT shader, because it’s modular and easy to use, and you can add an endless amount of extra LUTs with it. It might be that it conflicts with a specific version of the older MultiLUT.fx shader, but I’m not certain what’s behind the issue since I have the latest MultiLUT.fx shader installed alongside Prod80′s and I don’t get any crashing.

Nevertheless, if you experience crashing, open your d3d9.log file and scroll to the last line. If it’s the same as above, delete MultiLUT.fx and it should go away.

If you use any other presets that require MultiLUT.fx I can walk you through porting those settings to Prod80′s shader instead, so all your LUTs use the same shader set from now on for maximum compatibility (it’s very easy!).

Hi anon! I’ll do a proper tutorial on this at some point with pictures and proper steps etc, but in the meantime…

If you’ve made multiple luts you paste them together one under the other in one large png. Take a look at one of my multilut pngs and you’ll see what I mean.

Then when you have your multilut png you can edit one of the multilut shaders (I favour the one by Prod80). Follow the format it already has. You’ll need to point it to your multilut png, and tell it how many luts are contained in it.

Then you’ll need to add some kind of name for each of the luts (this can just be 1, 2, 3 if you want, or a fancy name like Princess Delilah’s Orange lut, Prince Caspian’s Blue lut, etc).

The format will be as follows:

“Lut 1/0Lut 2/0Lut 3/0”

Each lut you name must end with /0 - that’s how the shader knows it’s come to the end of that particular lut’s name.

Then, in the shader details in game the drop-down menu to change between the luts will have Lut 1, Lut 2, and Lut 3 listed.

Does that make sense?

If in doubt, use Prod80’s shader and take one of my recent multiluts and just edit it with the details of your own new multilut png.

I made my own reshade a long time ago using your Bloom MultiLuts I think. It's a MultiLut that has all these interesting names like Carina & Cassopeia etc (if I remember correctly haha).

When I updated my reshade & installed the prod(?) MultiLuts, to try out your S-drama & Moods, it doesn't seem to work? 🤔 My reshade kept saying the MultiLuts of these two couldn't be loaded. Is there a step I miss?

& I also lost my old MultiLuts that have all these choices during the process haha. But luckily I had a back up before updating. Phew. Which is why, now I think the Multiluts are probably not from the original set but are yours. 🤔 (But after redownloading I'm not sure anymore haha)

Also, the current reshade (that I made) uses Technicolor 1 & 2, DPX, Levels, Curves, the Multilut I mentioned, & maybe LumaSharpen (not sure if I do have it on tho) during gameplay. Are these combinations ok for the the pc? So far my laptop & game runs fine, but I want to be sure.

Also! If the Multilut I used isn't yours, do you know where it belongs to?

Thank you in advance! & Hope you have a great day 💕 I really love your screenshots btw! I think they'll make great wallpapers or loading screens!! 🤩

Hi there anon, sorry I didn't answer this sooner.

Have you downloaded Full Bloom 2.0? It uses the same LUT shader as S-Drama and The Moods, so it will be cross-compatible with them. Try taking out the old version and using this new one instead.

It's a great idea to use Prod's LUT shader because you can add as many new ones as you want really very easily, and know they will all work alongside each other. If you're making your own LUTs, I recommend doing so with his shader.

The other shaders you listed should work absolutely fine together for any type of PC. They're all simple shaders and don't require much processing power at all.

Hi anon. Have you tried using prod’s lut shader for it like I do with my presets? You can have as many as you want then, and they all work side by side.

This is a new and different type of MultiLUT shader than the one I used for Full Bloom (and which I included in Clear Bloom). It uses a 2-part system, with a base shader containing the nuts and bolts (remember, base shaders end with .fxh), and an additional shader with the information about that specific MultiLUT atlas. It makes it a more lightweight and customisable experience, because once you have the base shader ( PD80_LUT_v2.fxh) you can add any number of shaders for additional MultiLUTs as long as you follow the format in PD80_02_Bonus_LUT_pack.fx. You also, of course, need the corresponding MultiLUT atlas png, which in this case is  pd80_example-lut.png.

Take a look at this github repository. There are hundreds and hundreds of LUTs across multiple MLUTs for you to play with. 

You need to put the  _BaseLUT.fxh* file in your Shaders folder - this is what tells each individual MLUT shader how to work. Then, you can place as many or as few of the individual MLUTs in your Shaders folder, making sure to also put their corresponding png in the Textures folder.

If you want to try them all out I recommend doing so in stages so your ReShade menu doesn’t get overwhelmed with all the files. You can add and remove shaders while your game is running, tabbing out to the shaders folder and adding or removing them as you want, and hitting Reload at the bottom of the ReShade menu when you tab back in (that final step may not be necessary if you’re playing in fullscreen, but if in doubt hit Reload anyway).
