Vray crashing SketchUp

dane.teegardin · 6 Jan 2014, 06:56

Ive been running into this problem alot lately and was wondering if anyone has some suggestions. Ive been working with large models in Sketchup, usually around 100mb. Ive been using Vray plug-in to render these images. Some of the vray materials I made myself using fairly high quality images, some I downloaded from the chaosgroup website and others who have made them. When I go to render the scene, Vray will cause SketchUp to crash. Ive been trying to troubleshoot this problem for some time now, but it happens at different stages of the render so I cant find where the problem originates. Any suggestions on vray settings or tricks to make these renders come out would be appreciated.

Thanks
-Dane

Seems you answered your own question. All of these things will crash a render. Dont forget, you are still stuck withing the confines of a 32 bit program (SketchUp)

My advice is to render straight to EXR using the Render to VRIMG feature. Tick on Preview so you can see the progress. When the EXR file is saved, you need 2 things to open it

Photoshop CS5 or higher 64 bit
ProEXR installed for Photoshop

Without this, you will not get your render channels.

Alternatively, you can render to VRIMG and use the utility to get your channels. I prefer EXR, but either will work.

You also have the ability to render your scene using the DR Spawner locally on your machine as a 64 bit process. Just tick on DR, tick on Dont use local machine, start the 64 bit Spawner on your local machine, and then make sure local host is ticked on under the Hosts.

Thanks for the advice, I never thought of using DR on local. I will definitely try this out in a bit.

I cant take credit for it. It's a new feature in VR 2.0 that isn't discussed a whole lot, but its purpose is to render to 64 bit. The only problem is that you dont get to see your LC pass, so you have to wait for that to run before you see your preview in the VFB.

I tried to use the DR on local and came up with a couple issues. I cant seem to get the local host to show up, but I know I have seen it there before so this is confusing. I instead rendered using the local ip address on my computer, but it seemed to not render all the materials (The white on the facade is supposed to be transparent to make a screen texture). I have "transfer assets" on in the vray settings since I keep my textures in a folder on my computer. The good news is that the render didnt crash this time at least.
