Proper Texturing Workflow for Unreal Engine

[Thomas_Mansencal]

@daskyler

To make sure I’m interpreting this correctly: you’re advocating avoiding touching any of the filmic curve parameters UE exposes like slope/toe/shoulder, since that is meant to be a fixed standard, and any adjustments to be done through LMTs (UE’s color grading categories)?

Exactly! It is entirely fine to play with exposure though as you author your assets, you should do that all the time in fact, check that they look great at any exposure value.

@daskyler

the original rock texture done in Substance, using their default linear tonemapper, had a lot of colour detail that ended up disappearing after tonemapping.

It could be either that the albedo values are too high or that the lighting intensity/exposure of the scene is too high. Hard to get a solid answer without seeing the texture or asset.

@daskyler

And we should author based on no changes to the color grading categories & the default ACES curve.

Ideally yes, see it as your neutral authoring conditions.

@daskyler

I read the UDN link - to disable these changes, you locally modified the PostProcessCombineLUT shader, correct?

You can actually set them to 0 in the PostProcessVolume Actor:
