OctaneRender™ Standalone 2.22.2

[useruser]

hi everyone,
it seems that v 2.22.1 needs a lot more memory for geometry
i already posted that in the c4d-forum: (alembicfile included)

Could you send us the scene please so we can have a look? Thank you.

hi abstrax,

you only need to import the alembicfile and start render (downloadlink for the alembicfile is in the original-thread) no lights, no textures, only geometry and you can see the different memory-usage between 2.21.1 and 2.22.1
btw. once again a nice update. thanks a lot octane-team!

Sorry missed the file. Thank you.

Having trouble with more complex scenes with scatter nodes, and groups of objects.
Sometimes when I add a new object or refresh a mesh, the scene doesn't update.
Other times I replace an orbx in a scatter node, and textures get completelly mixed in other scatter nodes meshes.

ie. I have some palm trees. 3 species, 3 scatter nodes, I replace one of them with some flowers, suddenly one of the palmtrees becomes pink, because it is using the other mesh texture.

Hi abstrax...I think the render animation script is not working well....repeat the same frame..

[*] Improved Fresnel reflection for specular and glossy materials. Until now the code assumed that the light was always polarized perpendicular to the reflection plane, which is usually not true. As a consequence, the Fresnel reflections were too strong at medium viewing angles (see http://render.otoy.com/forum/viewtopic. ... 39#p227739).

It's nice to see this fixed in glossy materials! I did some tests a while ago and found that octane's fresnel was matching an S-polarized curve, while the other 3d applications I used match a non-polarized (averaged P and S) curve.

I have always adjusted the glossy material specular value down to compensate for the extra bright fresnel in octane, but I may not need to now.

Hi,

Dirt texture doesn't provide the same result with 2.17 and 2.22.1 (see attached images).
I added dirt texture on the pavement.

2.17

2.22.1

Can't reproduce the problem here. When I open the Alembic file in Octane Standalone 2.22.1, the geometry takes about 1.7GB. The same amount as in 2.21.1.

ok,
so this seems to be plugin-related.thanks!

I stated what was wrong back in September glad they finally decided to listen .
