Bug in Shader on certain devices

[royibernthal]

Here's a PG of the shader:

On an old laptop (Lenovo G770) it works fine.

Graphics Card: AMD Radeon 6600M and 6700M Series

On my new PC, it looks like there's a bug.

Graphics Card: NVIDIA GeForce GTX 1060 6GB

This playground uses a custom shader and not one provided by BJS could you confirm the issue with standard or pbr materials ?

[royibernthal]

Yes it does use a custom shader, I didn't encounter this problem with any built in bjs post process.

I'm not sure how to do that, can you walk me through it?

[Sebavan]

Ok thanks, at least it is not an internal issue in BJS but in the custom shader only.

It seems to be a bug in your own shader. What if you use regular material instead of your shader?

 

[Guest]

Actually after checking it more it seems that your shader does not contain code to support bones

[royibernthal]

Can that shader utilize bjs internal bones shader algorithm or does it have to add support for bones from scratch?

[Guest]

Nope it can reference bones like stdmaterial or pbrmaterial do (not trivial though)

look at all examples in the material library:

[royibernthal]

I see, would you consider it a considerable amount of work to add bones support to that custom shader? (not that I'm asking you to, just curious)

[Guest]

not at all.

As long as you copy/paste from the simple material I referenced it is one hour work (a bit of shader and an a bit of js code for the material)
