Hi guys, I’m wondering if anyone can advise on the handling of large cad data exports? I have an fbx of a car which is 700mb ‘full car, interior + wheels + body’ This file is incredibly slow, max becomes unresponsive/ unworkable, If i take the body on its own the fbx is 200mb, This works fine, I…

I’m not sure if the Quadro card is part of the problem… John, why would you want to weld the vertices in Maya? Just curious. In my opinion you loose the ability to select elements of the mesh that were originally the patches in the CAD program before. I often need to select parts of the mesh for th…

[image] Vray 3.0 Matte Properties and Reflection I’m really interested in how you deal with the Maya meshes in Max. I’ve always found that trying to do anything with them (welding, smoothing, resetting xforms, etc) just messes up the smoothing and leaves me with artifacts everywhere. For that re…

Interesting. It’s not something I’ve ever used, so I’ll have a look. Welding inside an editable mesh/poly or using the vertex weld modifier has always caused me problems. Just to clarify, I don’t mean subdividing. I mean using the smooth modifier in Max to get rid of faceting and/or jagged reflec…

It works. In the merge section, tick merge vertices and set threshold to 0.0. Also, keep normals and protect normals should be checked. Leave everything else at default, press calculate. The amount of vertices should be reduced significantly while everything else should look exactly as before. No a…

[image] Sun&Sky and HDR doesn't match Please make sure to right click->convert. It really makes a difference. Slapping and edit poly modifier on top of edit mesh instantly breaks normals. Very interesting. I always assumed they’d do exactly the same thing. Cheers, John

John and Oliver, some interesting points you bring up there. I have a question for you both. What if, I get the RAW CAD data, not Maya files, and not exported from Maya to fbx, but the RAW Catia 5 data (or in some cases the STEP files) How do I get that into a usable form into Max, considering I d…

Most of the Maya files I have used geo wise come in just fine, ‘fbx - media/enetertainment preset’ in and out nothing else needed regards to smoothing etc, If you was delivered a raw Catia file, I would imagine you would need a new pair of pants and a lot of time, not typically done from my experie…

How much can I expect to pay for a typical exterior car model, if I have to get somebody like RTT to prep the RAW catia for me and deliver a MAYA or FBX file so I can take it from there?

I guess a couple of weeks, best case.
It’s feasible on some jobs, not on others.

Cheers,

John
