Big mirror problem

[carconcal]

Hello friends, the cause of my post is because I have a new vray 1.49.01 problem. I am trying to renderize a room wich has a big mirror on one of his walls. I dont know why when i apply the material and send to render it close me the sketchup. First it waits a lot and then it brings back the vray frame and instantly close sketchup. The problem is that when I apply white material to that wall ...it gets me the render.

here i post some infromation could be for help:
edges 5335017
faces 2773106
component instance 9484
groups 2473
materiales 129

and i am using a Mac pro core I7 with 8 GB in ram 1067 Mhz

Hi

That seems a lot of textures for a simple scene. Are you using any very big textures or pngs. Can you simplify it a little? It will not just be the mirror but cumulative effect of textures. Would this normally work on your machine? I found if I have too many glossy surfaces I did not get a render! Can you use layers to hide something? Looks like not. Have you tried using ThomThoms clean up? I do not have the technical knowledge of others here but sounds very heavy for a single interior scene.

Someone with real knowledge will answer I am sure.

Carlos. You could build a Boeing 747 with fewer components and groups. Is this just the one room or is there a large resort complex as part of the file?

I agree. When I do little rooms like this, I copy the model out and delete everything that you dont see in the rendering. Vray for SU looks at the entire model when it parses, so even if you have stuff on off layers, it doesn't matter. I would copy out to a new file, and purge all as well as using Thom Thom's cleanup plugin. Then I would just look at my textures that are left behind and see if there are any large ones (over 1000 pixel in either dimension) and reduce those. I also found that if you are using TIFF files for textures, it can cause issues.

off layers do work. vray only processes layers that are on. I've verified this, don't have the link, but it was on the asgvis forum.

Fernando mentioned in a recent tutorial that even off layers are considered when parsing a file. He said that he deletes everything he is not using in a scene and saves a separate file as part of his workflow. I have noticed much faster parsing times when you do this. Not necessarily faster render times though.

That was my experience, I was checking parsing time, and it ended up being about identical with layer off versus geometry deleted. There may be issues if there are extra materials that are in that off layer, it may be that processing materials could slow things down too.
Found the thread. Man, I wish they would fix the old links!

Maybe I'll bump this for Fernando, I am very curious to get an answer from someone who knows...
