OTOY Forums

Thanks for the suggestions guys.

Sadly no success yet, turning smoothing off (both in the plugin as well as in DS itself) for the building geometry had no effect at all.
Conversion to subD only made the triangles smaller, at the cost of ugly distortions because there are no edge loops to support the angular geometry.
Selecting 'Bilinear, Sharp Edges and Corners' kept those distortions to a minimum, but the result is unacceptable none the less.

So it appears that only a substantial modification of those objects in an external modeler could possibly help, not a solution for every user, and certainly not a great time saver! Again, LuxRender had no problems rendering these buildings at all.

I cannot imagine this is not a serious defect for people using Octane for rendering SketchUp geometry (and similar 'sparse' models), so I'll have a look in the forum sections for the other plugins to see if it is mentioned there at all. Finding a quick and simple fix would be nice too of course : )

Cheers!

Hi Erik,
Are you sure you don't have duplicated geometry there? Faces on faces?

Seeker

Thanks for your response Seeker,

Faces on faces, looking at the way these building's textures are organized that's most likely part of it.
I'll look into it later, for now I'm having a ball experimenting with the material editor : )
(between the frequent crashes you're all too familiar with of course)

Cheers!

Erik

There may be lamina faces, non-planar faces or else the normals are messed up.
One other possibility might be extruded faces that are sitting just on top of other faces.

I you are having frequent crashes, check you VRAM usage. Trying to use more than 100% is the only thing that actually causes crashes for me.

Hi Doc (?)
Most, if not all, crashes occur when I try to change a material type in the Nodegraph Editor.
And at this stage of my experimentation I do that a lot, so it happens a lot.
With some objects/materials it seems to happen every single time, others I can change without any problem after starting DAZ Studio again.

I have provoked a VRAM-crash a few times, just to see what would happen, but then it's the nVidia driver that "looses contact with the application" which then takes down Studio in kind of a controlled manner, not the sudden crash to desktop when the NE stumbles over its own feet.

Fingers crossed that the next version has a better sense of balance ; )

Cheers!

Erik

Ah yeah, that's true, I have actually had that happen a too.

did you check that rayepsilon thing for the issue ..

@ acc24ex
No, I haven't yet, mostly because I haven't got a clue (yet) what it does.

First thing I want to try is remove any stacked layers of geometry and see what happens.
These two buildings appear to have kind of an odd structure of wall and window layers which could possibly make the surface 'undefined' for Octane.
Again, these buildings render just fine in LuxRender.

As for those crashes: I'll try that Latency setting Linvanchene suggested, perhaps it helps improve stability.
Thanks for the help guys.

Cheers!

Erik
