Re: Shadow Terminator problem

I am not sure if this is relevant to the currently discussed Bump issue, but I don't appear to be getting any Bump effect be with the Checkerboard Texture like it does with other textures such as Distorted Noise? This should be normal: the bump is proportional to the difference of 2 adjacent pixels...

Re: PathOCLBase kernel compilation error

It was just a typo in OpenCL point light code, it should now work fine.

However while NVIDIA and Intel were just printing the correct error message, AMD compiler was spitting out what looks like an internal error.

Re: Shadow Terminator problem

Can you do a test using an UV scale of "1" (i.e. no scale) ? I'm pretty sure you will get the same result out of Cycles and LuxCore (shadow terminator aside). LuxCore scales the strength of the bump by 10 if you scale the UV by 10 . This is a side effect of how the code is written (and probably was ...

Re: Shadow Terminator problem

same scene, opened and rendered with cycles, same texture, same mapping and I tried to match bump strenght as best I could. With luxcore those dark areas appear even with very low bump values. Your LuxCore material has 10x UV scale applied: desktop.jpg I have no idea how to check Cycles settings bu...

Re: Luxcore direct light

But i don't think it is like you say. just test it and Cycles 0 bounce match luxcore 1 bounce visually. You can not do LuxCore 1 bounce if you are using Blender as I have explain. Just export the scene in text format, open the .cfg and check the value of "path.pathdepth.total". It is 2 even if you ...

cycles full lighting:

luxcore full lighting:
The bump mapping scale of LuxCore scene is something like 10x larger, are you sure it is the same scene ?

And Cycles is clearly lacking of the Shadow Terminator fix:

Re: Luxcore direct light

First of all something about all the direct light tests I have seen recently and I'm sure you are not aware: when you set max. path depth to 1, BlendLuxCore exports a value of 2 (I think it always exports "n + 1"). Why ? Because so you can have MIS and MIS is pretty mandatory to render glossy surfac...

Summer vacations 2019

Many developers will be out of the town next week(s) for some summer vacations so questions may receive slow or no answers for some days.

Re: Shadow Terminator problem

As far as I can see, the problem is in the old rendering, not in the new one. This is a rendering with old code (different scale and lighting just to show better the topic): old.jpg See how all bump image pixel are lighted ? This should ring a bell, with a such brutal bumps, something should be in s...

If he doesn't use any OpenCL engine and disable it in the imagepipeline, he should be able to use the OpenCL version, no?
I'm afraid you get an error for the missing OpenCL-related DLLs as soon as you start the executable.
