behavior is identical on 2.78c

David Weese (DavidWeese) added a comment to T34101: No alpha on OpenGL renders.

I apologize if this is posted in the wrong place. This *seems* like a bug. Using Blender 2.78.4 which I used instead of 2.78a/b because prior to 2.78c IK was broken and causing crashes. i will test on 2.78c asap.

Sergey Sharybin (sergey) claimed T51007: Material viewport mode crash on node with more than 64 outputs..

The issue is coming from hardcoded MAX_SOCKET set to 64. I've tried to remove such a static limit, but it's not so trivial within the current nodes design, especially for the texture nodes. I think it is safe to bump this constant to 512. This will only be ~16K extra stack memory usage per thread during evaluation which is really small for the modern systems.

Lex (Lex4art) added a comment to T51008: Normal map with bold relief causes black artifacts with Glossy BSDF shader.

I also have struggled with this kind of artifacts and found a simple trick how to avoid them. Basically you can calculate a dot product between normal and incoming vector and attenuate the normal map where it could cause problems viz https://blenderartists.org/forum/showthread.php?382497-Black-material-artifacts-on-flat-angle-surface-areas

Lex (Lex4art) added a comment to T50674: Pointiness artifacts in Blender v2.78b.

I can reproduce the issue with 2.78b, but not with 2.78c and master.
Please try updating to 2.78c and checking if it also fixes the issue for you.

Lukas Stockner (lukasstockner97) closed T51008: Normal map with bold relief causes black artifacts with Glossy BSDF shader as "Archived".

This is the same problem as in T49921 - the normal mapping changes the surface normal, so the reflected ray would go inside the actual geometry, which isn't really possible.

Lukas Stockner (lukasstockner97) triaged T51023: MixRGB node still keeps in memory both input textures no matter what "Fac" value is. as "Confirmed" priority.

Lukas Stockner (lukasstockner97) added a comment to T51023: MixRGB node still keeps in memory both input textures no matter what "Fac" value is..

The problem here is that you have Clamp enabled, which means that the Node is actually doing something (or rather, would do something if your textures were HDR).
However, there's no real reason to keep the full MixRGB node in the SVM code if only a clamp is needed, so I'll add a separate clamp-only SVM code.

Robert Fornof (amdbcg) added a comment to T37953: Separate sun lamp size as angular diameter.

https://developer.blender.org/D229

intern/cycles/app/cycles_xml.cpp 	
/* Generic */
 	xml_read_float(&light->size, node, "size");
+	xml_read_float(&light->sun_angle, node, "sun_angle");
 	xml_read_float3(&light->dir, node, "dir");
 	xml_read_float3(&light->co, node, "P");
 	light->co = transform_point(&state.tfm, light->co);

I cannot find any of that block in :
blender-build/blender/intern/cycles/app/cycles_xml.cpp Did it move or get re-done?

  1. I will work from Samarth Mediratta's diff , and modify as needed.
  2. I will create a demo video when it is ready for review.
  3. I will hand this back if I cannot complete 1. or 2. by April.

LazyDodo (LazyDodo) added a comment to T50676: Crash on closing while frameserver rendering.

I remember looking into this, the problem was audaspace is being shutdown on the mainthread, but then the render thread does a audaspace call anyhow, null-refs and takes down the process.

I believe these settings are now in Render buttons, Geometry panel. @Sergey Sharybin (sergey) maybe would be worth noting that kind of UI change in release notes?
