Bug ID: 107454 Summary: BLENDER 2.8 principled BSDF shader and shadow are broken in EEVEE on mesa gallium r600g gpu Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: amonpaike@gmail.com QA Contact: dri-devel@lists.freedesktop.org
on the new blender 2.8 under development some shaders and projections of shadows are broken .. I do not know how to describe the problem technically, I have already reported the problem to the bug list of blender developers, although I know that the problem is probably the mesa drivers, because on my laptop that has two gpu, with the intel gpu the graphics is perfect, with the gpu amd I have these problems of shading. For a specific description of the problem, refer to this bug report https://developer.blender.org/T56211 (the tests were done on the latest mesa drivers built daily by padoka ppa, with the stable drivers of ubuntu 18.04 eevee shading was totally unusable, so the situation has improved significantly)
