OctaneRender™ 2020.2 RC7 [obsolete]

[jobigoud]

I had a look a the scene and the file "tube_opacity.abc" has a vertex attribute array "opacity" of type float64 (double). As we currently don't support float64 attributes, it doesn't get loaded.
From where is this file exported and do you've got any control with which data type float vertex attributes are exported?

Ah, that's why I couldn't make it work either. The files are most likely coming from Quill's Alembic export, there is no option to change the data type in the export dialog.

Yes exporting out of Quill.
Thanks for clarification. Makes sense! What float type is supported, float32?

This might not be relevant for RC7 so my apologies but I wanted to know if there is any way I can set the "cycle type" to "loop" for animated alembic imports?

Yes only 32bit floats are supported right now. Will try to extend that to float64 (converting down to float32), but haven't had time yet.

That is not possible unfortunately. You would have to bake that into the file during the export. We are planning to allow time transformations and looping of nested node graphs, but we are also planning a lot of other things so I can't say, when we are going to be able to start working on that.

Fortunately it was a fairly simple change and will be in the next 2020.2 release.

Was trying out Random Walk on a specular material. Seems like there are some smoothing problems when you got up close.

Is it possible we could have the scene please? Thanks in advance.

Haze, this problem has been brought up before (see viewtopic.php?f=9&t=74760 )

I'm not sure if Zay sent you his scene, but I have also attached a simple scene demonstrating the problem.

The higher the medium density gets, the more faceted the surface appears. You can subdivide the mesh more to try and work around the problem, but this is obviously not a great solution (scenes get very geo heavy).

1. Load the orbx and select the render target to start rendering
NOTE: Both spheres use the same geometry. The left one has a glossy material, while the right uses a specular + random walk
2. Select mat2 > medium > and adjust density slowly from 10 to 500.

RESULT: At 10, you dont see any faceting. Once you start getting to around 100, faceting appears.

Yup, I sent him a PM. Not just in random walk I see this. Seems like it also have to do with indirect light and how light is falling on the object.

Ran into an Error with loading render states on several scenes now.

When scattering an object, is there a way to avoid objects being scattered in the same position?
Here are about 4 objects (ferns) scattered in the same place.

Which distribution model did you use? Surface area and Relative density should produce better scattered objects. If you use one of these and you still have 4 on the same place, maybe there is a bug somewhere, in which case it would be good to have the scene so we can investigate.

Thanks for the report. This problem will be fixed in the next release.
