BUG:

OctaneLight has no size when opening a scene from Octane 2025. But it is displayed with proper size in viewport. Had this in several files now.


Hi mbetke,
Thank you for reporting this issue.
Sorry about that.
We also noticed this, and this will be fixed in the next release, 2026.3 - 26.8 ...

Hello NeonZorblug, is there anything you can do about it or is it a standalone limitation ?


It seems to be a standalone limitation. I could reproduce the issue with a more simple case, without tyFlow and will check with the engine team.
For now, the best option is to use the Vertex displacement ...

It's kind of working but only with these weird settings and not as it should (the black disk has motion blur, it shouldn't).

I've always used around 0,5 to 2 MB Duration in Octane with shutter time between 25 and 150, as soon as I put these value nothing is working correctly.

I have correct ...

I've tried every settings available (mb duration, shuttertime etc...), nothing works when the displacement map is there


Thank you for your scene.
That's very strange.. I'm not sure why, but it seems to work when you change the Texture displacement's Quality from High to Normal !
That could be a ...

Hello,

Motion blur doesn't work with displacement, please see attached video and override motion blur in cameras is broken again :


Hi remKa,
I’m unable to reproduce the issue on my end, it seems to work fine here. Could you share an example scene that reproduces it?

Thanks. I thoughts it's a problem on my side with the Corona Update I did. Glad it can be fixed!

I did some manual adjustments for now. Corona Materials are very shiny usually with a roughness set to 0.0 all the time, which makes it neccesary to adjust them all one by one after first conversion ...

I made upgrade to this version and also updated to current VRay and Corona renderer. I don't have license for them and never use them but as far as I know they are needed for material conversion.

Now I have problems that the material is unsupported. But it used to work for years before. This is ...

By the way, was this ever added? I thought I saw a post where it was added https://render.otoy.com/forum/viewtopic.php?p=443422#p443422
Trying to achieve the same in octane like they did in vray not sure if octane can do it https://www.youtube.com/watch?v=-0Qa600Z9FM

Thank you


No, this was ...

Hi,

is there anyway to add octane volume mesh as custom reference object inside tyflow?


Hi coilbook,

No, not currently. I'll ask the engine team for a future addition.
That would probably be using the 'Mesh volume SDF' type, and would also work for Vectron objects. but I'm not sure if that's ...

There is a bug. When the scene is reopened octane auto adds xyz to uvw to projection. If you clear projection to none and reopen the scene it will go back to xyz
Texture wood> Amount> input B > Projection


The scene is attached.


Hi coilbook,
Thank you for your scene.

It might comes from the ...
