Text Meshop Crashes Octane

Hey Paul,

if i use a Text Meshop and Start the Render Modo Crashes suddenly. I have to add a freeze Meshop to prevent this. Would ist be possible to make a warning sign or remove this bug?

Edit: Matt Cox wrote on Slack:
"Modo supports many polygon types; from simple faces, to subdivisions, to more complex things like b-splines, patches and text. Modo has code used during rendering and drawing to convert these more exotic polygon types into triangles that can be interpreted by OpenGL, or be intersected by rays for rendering.
If Octane goes through the standard surface API to get the surface, this will be done for them, but if they read the geometry via the Mesh API, this will not be the case, and you will have to manually triangulate the text polygon into something that octane supports."

I also bugged this a year ago and I'm waiting for a fix.

It seems to work sometimes, but crashes once you edit the text.

VRay renders text polygons (and meshops) correctly without needing any manual freezing/triangulating.

For now, I just make sure to add a freeze meshop above my text polygons, but if you forget, modo crashes and you potentially lose work.

Hi - I bugged this with Foundry a year ago, so I will need to go back over everything to work out the status. Will get back to you early next week.

Thanks

Hey Paul, so you already use the standard surface api? Thank you for looking into this!

Hi

I have double checked this issue against the bug submitted to Foundry, and they are the same, so it is an issue that Foundry will need to resolve.

In the meantime, please use the work-around proposed by Funk, or turn the Render Cache on.

Thanks
