HDRP+ TMpro + Postprocess - Shader Global Keyword limit

Unity Engine

Hi,

First thanks for your time, I search and research this topic, try a lot of solutions and spent a lot of hours, I know the need of using local keywords (I can’t in some cases are external really complex assets), but I reach a point where I need some help.

I have a problem with the global keywords in the shaders. I have been checking the project (I have shader control, and some forum tools also), this tools reports that I use around 60 keywords. The problem is that I reached the 256 keyword limit, but what I’m afraid is that most of them are unity built-in keywords,

I’m using HDRP (7.1.6, Including layered lit) + TextMeshPro (TMpro) + PostprocessV2 (PPv2), I strongly believe that I’m using less than 60 global keywords, so the total number of global keywords that this "unity built-in combo " are using is around ~200 keywords it means that I have 19% of the total keywords available and that is really low, moreover if I want to use assets from the store like CTS or vegetation studio.

Also in the console error appears used keywords that I don’t use anymore like some AURA keywords (but they are just a few…)

I have Unity (2019.3f1) and all the packages updated, restarted unity and test a lot of things.

I’m doing something wrong?, this is normal?, what I should do?

How many Keywords uses HDRP?
How many Keywords uses TMpro?
How many Keywords uses PPv2?

I would appreciate any help,

Many thanks.

Did you know, that you don’t need PPV2 because HDRP have it’s own postprocess? PPv2 don’t even work inside HDRP. Just asking.

ouch!

As the moment I read you is crystal clear, many thanks!!

In the end I think I knew that the HDRP uses its own PP but somehow my brain think it was the same PP from the package manager not a fully independent one… thanks for point it out!! , for me solve the problem!

I think that a clear notation in the HDRP documentation (something like, remember to get rid of the PPv1 and PPv2) would be much appreciate :slight_smile:
