Re: Can't sample textures in ShaderFX custom code
Got it. For some reason this is missing from docs. Docs include code for GLSL_4 that only works in swatches. The code for GLSL_4 uses the texture node: float3 t = texture( SFX_TEXTURE0, float2(UV.x, 1-UV.y) ).xyz; While OGSFX uses the sampler node. float3 t = texture( SFX_SAMPLER0, float2(UV.x, 1-UV.y) ).xyz; Problem… -
Re: Can't sample textures in ShaderFX custom code
Thanks kodde! Not so quick was banging my head against the wall for about 4 hours before coming here haha! I mainly use it to get dimensions so I dont need a toggle to enable texture maps. But there is a problem, swatches dont use OGSFX, so you lose the ability to check for compile errors, because every OGSFX code turns… -
Re: Can't sample textures in ShaderFX custom code
There is a env variable you can enable so that Maya prints out any compile errors to the shell. Maybe that is helpful? (ShaderFX tells you what that env variable is when you first open the UI) But if you want to support all the different viewport modes that Maya has, then you have little choice but to add code for each… -
Can't sample textures in ShaderFX custom code
Hi There! Been porting my shader for Opengl for compatibility reasons. But it seems I cant sample any texture in custom code. Not even Autodesk example works, even though it works in the shaderfx swatch. It works with OpenGL legacy, seems to be a problem with OGSFX Did anyone have this kind of problem before or know whats… -
Re: Can't sample textures in ShaderFX custom code
Well that was quick. I was going to say I haven't dabbled with sampling textures with custom code. Good to hear you solved it. -
Re: Can't sample textures in ShaderFX custom code
BTW, this is What I am doing right now. A script to automatically connect substance painter textures to an arnold shader, then create a shaderfx preview materials with attributes linked to the arnold shader, so when you change one the other changes too, aiming to get as close as possible to the arnold render. Left is the… -
Re: Can't sample textures in ShaderFX custom code
Thanks Kees! Thats very helpful! Since you are here, haha, let me seize the oportunity! Is there any hope that we get area light corners? Maya viewport has access to it, and preview it correctly, its exposed in the API. And maybe one day access to the framebuffer? It would be awesome to prototype full screen effects in…
