Did you assign V-RAM in Windows?

I also had some scenes which froze my laptop with 16GB (14 usable) and after assigning V-RAM scenes worked good. Try this. If not, your trees might be Laubwerk and you lack physical RAM.

I have this problem with large models and plenty of scattered objects, lots of textures and high definition settings. At some point, sketchup starts to flicker in the background, but V-ray keeps on rendering.

When I hit batch render and leave the computer awake for the night , sometimes it freezes and only 3 of 5 renderings make it.

Most of times , V-ray uses all my 16GBs of ram and portions of assigned Vram.

hello,

I knew of a software which made a transfer between v-ray sketchup and v-ray max properties, just that I miss its name at this point. It was a script for 3ds max which imported material properties such as glossiness factors and bumpiness slots...

Though it can't be FULLY compatible since 3ds max is a different modeling platform than sketchup and will never be completely compatible with, also v-ray for sketchup is totally different than 3ds max one.

And if you know your parameters you can apply them in v-ray for max too . I know you don't like working twice on something, but that's the best way sometimes.

hi, i'm starting to use sketchup vray 3.0 and i'm trying to use the cut tool to render it, but when i get it finish the image is not quite good. it has ghostly plains in the main section.
in the pregress windows apears this txt : Scene bounding box is too large, possible raycast errors.

some one knows how to fix it?. attached images in this post!

good find.

I'm getting the same glitch when trying to render 3D plans/ dimetric perspectives using section tool.

Hope there's a fix for it.

Hello,

I have a model of a random building, and I'm trying to achieve rendered elevations using a spherical light as fake Sun.

This spherical light is inside a group with a reference axis so it is rotated in ways all elevations can receive light, assigned to a layer i.e. SUN EAST/ NORTH ETC. I hide the unnecessary layers within the specific elevation scene, but when rendering, V-ray shows light from all spherical lights, even if they're hidden/ deactivated layer ... tried both ways > layers or hidden group which contains the light entity.

Any idea how to solve this?

****I have managed to work around this by exploding & re-componenting the components - an understanding of why would still be great to know!

Though exploding the darn thing makes the leaves and other organic pieces look strange. I'm using mostly 2D textured leaves, but they look good before exploding, then everything becomes chaotic.

If the file is heavy - sometimes going from frame to frame in SU doesn't get synced properly with what is sent to Vray. SU camera is lousy.

Maybe try adding more keyframes so the swing in the SU camera is less dramatic.

Yes, the model is big, a mansion surrounded by vegetation (50%) proxies, facade details, and displacement materials like brick and roof cover.

Good, I'll try that... thanks

There is a problem though. Frames were rendered, but some of them are tilted, any reason why?

When merging the frames in post processing video sequences appear tilted, and I've checked through each frame, finding some tilted frames which I was needed to remove and re-merge everything. Still, removing even one frame is noticeable wether the movie is in slow/ fast tempo.

Hello,

Tried to figure out how to create a fly-through animation with VfSu 3.4 following the 2.0 tutorials, but some of the settings do not show up on the interface, like "Don't render final image", needed to precalculate LC and IR.

Any workaround for this?

Everything else useful for animating walkthroughs is present : LC settings and IRmap seetings.

LE: Found it, VfSu 3.4 doesn't need "Don't render final image", it's only a few basic settings:

1. Irradiance Map - Disk Caching set to -Incremental add to current map-
2. Light Cache - Disk Caching -Fly throgh-
3. Animation -Entire Animation- and set an output file location

Hit render and it'll do the job. At first, a blurred image will show, then everything will clarify when V-ray goes through each frame.

It could be a trick faking the order of layers. You have your main diffuse, you add a reflection layer with a texture linked to it, then swap order of layers. Or, if this doesn't do it, make 2 Diffuse layers : one with color, one with a texture [like puddles, imprints]. swap it the way you like. Then drag-n-drop the bitmap slot of Diffuse in Reflection.

If that doesn't do it, you need to separately scale the puddle-imprint texture to your diffuse texture.
