Starting CADVRter beta powerful 3D/CAD/VR conversion

rv1974 · 12 Dec 2019, 17:07

ashraf, we desperately need rock-solid skp->fbx converter with 'combine by material' option , (smoothing groups and textures position is must too of course).
Is it doable?

This is already included you need to check the optimize for VR option in the FBX output settings.

As shown in the following image

Well I have bad results
40mb skp was converted to 800kb fbx (almost empty, some cameras and a couple of faces).
I could PM some examples, would you like to try?

Of course, this will be of great value for us.
Please send us the SKP and inform us if you were testing on Windows or Mac.

For some reason I could never get good results with any of SimLab converters (incl. Cadverter).
The main problem is it does not keep original orientation of faces.
When I import those fbx files (made of skp) into Max tons of faces are flipped.

I would be more interested in a good working SKP to 3DSmax file linking... The only solution i know is Mirza Link Manager, but it combines by material and doesn't support Instances...

I PM-ed you. Thanks in advance, Ashraf.

0 support there. He never answers. But the main issue is his Link Manager just freezes on more or less serious files. 'Combine by material' is the most valuable thing ever. If you need instances then open original skp in max. The problem is Max does not 'understands' skp hierarchy- only lowest level of instances will be kept.

I tested the model.
It worked with merging, took few minutes I will review more though it is a large model

Here is the result in Microosft Viewer

Following is result in SimLab VR Viewer

Will instigate speed more on Monday.

I re-checked fbx model both in Max 2017 and 2020. Normals are messed up everywhere.
Microsoft viewer does not indicates normals' direction (Maybe you've got Max installed by mistake?) There's a tiny chance that it's Max importer that spoils your fbx but I guess is not the case.
I expected to get an fbx containing approx. 50 meshes only (by the number of materials in file). I received almost 30K objects instead (mainly junk groups). Their creation must be blocked.
If you combine by material all those groups have no meaning!
3.Everything is badly triangulated.
I need object naming by its material name. Is it possible?
Thank you for attention

Thank for for the great input, most of those are easy to fix issues, hopefully we will be able to address them during the beta period, if you see CADVRter of value to you and you are interested in speeding things up you can communicate our suppor@simlab-soft.com

We will do our best to make this an essential tool that simplifies workflow. This being one of many many use cases that will be simplified.

I contacted supporT
Thank you

In addition to challenges I mentioned above:
5. 'combine by material' is not OK yet- there are still multiple meshes with the same material. The goal is one material=one mesh (meanwhile there are 60 materials and 140 meshes)
6. Insanely over-complicated hierarchy of fbx I've got (mentioned in p.2) leads to heavy lags
inside Max. It takes lots of efforts to delete all those helpers manually.

I'd seriously check the possibility to develop SimLab Skp-Max Link Manager (I mean a Max plugin, able to to deal with heavy geometry). It'd have a good potential

Thank you for the suggestion, though this is a great idea, our hope is to add more geometry processing for large models in CADVRter, so more users can benefit from it, using different applications, and going through different formats.

My suggestion is based on your background- you have tons of discreet importers\exporters for numerous programs (we bought some btw). Creating universal and flawlessone-click translator undoubtedly has a great potential too.
