Did you use the Sketchup Material Browser to change the color of the material? If that is the case then it won't change the diffuse texture for Vray. You would have to use Photoshop or similar to change the color of the diffuse texture of the vray material.

hi you can delete Lisanne(Sketchup mam) and go to windows-model info-statistics- purge unused materials. this will clean up all unused material in v ray material editor. [image: Drmp_1.JPG]

@pbacot said: I don't know what the name for this metal work is but why not use a texture that's already made? or start with one anyway and work with it in a image editor. Search on web for hammered bronze texture gives a lot examples. Or would these just not match exactly enough. Looks like for this piece a different texture needs to be used for the rim, but the base color would be the same. i already used hammered metal textures but it is not exactly matching. should i use any map like bump or opacity ? i am new to vray so please help...

Nobody ??

Post your SketchUp file and i Will look at IT. I think your power must power.

Cheers, I'll take a look.

Doesn't Vray render out numerous channels as passes? Shadows and Object ID pass for example?

According to official Vray Docs.: Migrating from Previous Versions @unknownuser said: Loading ‘.vropt’ or ‘.visopt’ files created in previous V-Ray versions is not recommended. Some outdated parameters may cause unexpected results. Using the new streamlined quality presets, and then fine-tuning the settings before saving them in a new ‘.vropt’ file is the recommended approach.

You just revived 8 years old topic Right click to image > Explode

i posted this on the vray section but thanks for the info, if i find the answer to this problem i wil post it here.

Try replacing the bitmap on the difuse layer to some other map, I did wth a "Checker" map. Render it, the put the a bitmap again and see if the image gets back to normal. It solved the problem at my computer using the 3.4 version.

For the emisive material, change the 100% (R0/G0/B0) black surface for something little more lighter, you will see the glow efect. For the glass, it's a reflective material, you made a single plane pointing the sky, its reflecting the blue of the sky, the material is correct. Try ussing it on a more complex shape, like a vase or something, and inside a enviroment with something that the glass can reflect. You will see a diferent result. Sorry for the bad english.

Search for "Clay Render" Tutorials. Try increasing the Size Multiplier of the sun at the light tab to remove the sharp shadows.

Thank you very much!

Hello, workin on the latest version in 2016 and can't seem to be able to specify a batch render file type other than the default .png, it would be nice to select the vray image file type to be able to go back in and make exposure etc. adjustments.

Hi, Refraction parameters and Opacity map values effect transparency. Take a look at this: VRay Material | VRayBRDF

looks cr@ppy- like a cg oilcloth. I suggest to download from vraymaterials.de some better alternatives (at least textures, since they are Max only), and watch zillions youtube material tutorials.

@siobhan said: ****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.

Hey Laurent, This is definitely a problem you'll want to email support@chaosgroup.com and tell them about. They are very responsive and will be able to sort this out for you.

@andybot said: 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
