Trnsforming Vertices... Taking Long Time

[jujubee]

I have two scenes full of polys on x64 - about a 100+ meg file each. But when I go to render them, it says transforming vertices on the render stats and just keeps going for like 5 minutes.

Daforce also experienced the same issue on x32 with a different file of his this morning (again lots of polys but instances), but I think he wont post cause he's saving post 5,000 for something special.

Same thing here,(x32). 2 or 3 scenes i've been working on lately which are full of proxy tree's.
Just thought I'd gone OTT on the tree models.

It has been noted before, I think; it happens because of a change in the 3dsmax 9 SDK. It is already corrected for newer builds, so you can email me to vlado@chaosgroup.com, if you wish.

Best regards,

I just paid someone to optimize my trees and a car library mostly cause of this. The funny part is that I had a much bigger scene that experienced none of these problems.

Oh well - emailed. Hope to get a newer build soon. Thanks Vlado.

It's not so much the amount of geometry as the way objects/materials are linked to each other...

does having many instances in the scene have anything to do with this? As I have noticed that on one scene in particular that i'm working on it spends ages transforming vertices, then a not quite as long time but still long enough on updating instances, then the render flies through really quick, so its been wait up to 2hours for the precalc and under a minute for actual render time at 640x480(this is with no Gi, lights in scene, and 1 std max material applied to whole model)
have sent you the scene and am keeping my fingers crossed!

edit: rc3 btw sry

I encounter the same problems down here.

Hope that there'll be a fix or workaround soon, 'cos I need many VRayProxies copied as reference for a film-scene.

I don't know if it's just superstition, but I've been putting the

gc()

in the listener window and hitting enter before rendering...it frees up the undo cue and seems to make for peppier render starts...

[domi]

ah will try that as well thanks

have similar issues especially when using DR...

Got loads of displacement modifiers? That causes this too.

yeah that was i thought too, but after merging all the xref it renders fine (still goes through transforming vertice session but lots lots faster to get through) ...might check if the object has weird material settings on them.
