I’m having a lot of problems rendering a blender fluid sim scene when I apply the glass and or water textures. I was able to render the water at one point but now neither material works. However, If I export the scene as an Alembic file and open it in Octane Stand Alone using the exact same water and glass material it render fine.

Please help me in determining what this is occurring. I can send sample files if necessary. Meanwhile, below are my console error messages:

Double check your ClearGlass and Water materials with the node inspector.
Looks like somehow there is an attachment that is "illegal".
Check the dispersion pin, the error is saying that there is an Octane Absorption Medium connected to that pin, which is not compatible.
The Medium nodes are for the Medium pin only.

I thought I deleted all the materials at least several times but this keeps happening. I will try again. I am not that experienced with Blender - still learning. Been a long off and on again process but I have come much further this time. Thanks for pointing me in the right direction.

Not sure if this is related, but remember: if the engine is updated and provides a new/different amount of node inputs and outputs, the materials from older files or the LiveDB may be broken, because the connects are bad ... check the materials. If they preview in Blender they're probably okay, if nothing happens etc, then there's broken materials to fix.

It is a bug in LiveDB specular material import. Will be fixed in next version.
Just reconnect the Medium node properly: to the medium input of the material.

Hey thanks Jim - that worked perfectly. Rendering out my first Octane Blender animation now
