Can you post screenshots of your material diffuse and material maps settings ?

Thanks mate, it's so helpfull Love from Indonesia,️

Thanks TIG, I had learned somewhere along the way to avoid small geometry...didn't know that it was an issue the other way around too. guess I overcompensated. But I scaled down and it doesn't seem to change the problems I'm having

Well, I hope your renders got out on time, but two quick suggestion I can make is to first, try deleting any lights in the scene. Sometimes lights become corrupt and cause a scene to not render. If that doesnt work, a last resort would be to go to Extensions> V-Ray> Debugging> Regenerate all materials. You'll have to re-build all your materials from the base diffuse layer up, but the model should render again. Let me know how it goes with the model.

Doh! I realized I can simply freeze vray via Preferences-> Extensions. Thank you for response.

@timothyfranks said: Hi All, I've had great success using the method caecarvalho suggested - however I have just run into the issue where the transparency setting in the Vray material editor only adjusts the brightness/contrast of the material i.e. 0.25 gives a washed out look, but no translucency. The Alpha layer still makes the correct areas 100% transparent. This seems to have happened for almost no reason i.e. models which have previously rendered perfectly now don't, and as far as I can tell there have been no significant changes to the models or to either the SketchUp or Vray programs. Any ideas? Hello Timothy, if I understand right,I see you're trying to adjust the transparency in a wrong way. The correct way would be to use the color parameter in the tranparency option and not the number. What I mean by that is, if you want a 75% transparent text, you need to use a 75% gray color. You can leave the value 1. You will use colors from white to black, being black no transparency and white full transparency.

@tedvitale_cg said: Try this glass out. You'll need to apply it to a thickened geometry for the refraction to work (model the glass pane), but it should give you a good starting point. Thanks for that, really appreciate it! I will get some rendering done this weekend using that glass.

Are you using the demo? The demo has resolution limitations.

Also by the looks of your Frame Buffer it's zoomed in 800% which is why its so blurry. If you click on your Frame Buffer window and use the scroll wheel to zoom back out to 100% is it still blurry?

probably need to go back to default settings and update camera, environment, etc. settings. There may be a bug that once you select other than RT CPU, the vray settings get messed up.

the problem can be by some things: improper geometry in one or more of your components, improper materials or the resolution and your configuration. improper geometry - Sometimes vray can't triangulate the surface. Check your geometry with solid ispector, solid solver or manually. Materials - Look your vray progress window. In the progress you will see which materials load fast, which slow, other don't load. For those that load slow, you can reduct the resolution and dpi of textures (both of diffuse, bump and displacement). For materials that vray freeze trying loading them, you must change them. It's difficult to find which material freeze exacte, because vray show you only treated materials, so you leave loaded materials and try to repair the others. The resolution can be a problem too. With my Radeon HD6850 and phoenom II x4, I have a problem last two months. There had a windows update probably and I have no updated catalyst, because AMD do not support catalyst any more. So the maximum of resolution of exterior render of complicated models its 1024x768 for me.

Thanks for all your advises. I decided to add photo outside the window, but it made my render look really dark, so I've changed the setting of the camera to: F-numer 8 Film speed 320 Shutter speed 30 There are some new stuff on the model, but in general it is the same model as in the first post. @rspierenburg: Firstly I don't take your advises personally, they were really helpful I've change all the whites and used different shades for wall panels, furniture and paint. You were right, it looks so much better Downloaded and used in the model, although I don't see much difference. Maybe my settings are incorrect? I've added some bumps etc. Changed to 65 @tparks It is on. Amount 0.6 Subdivs 12 Radius 30 - although I'm not sure if is it optimal. Render looks so much better now, but the shutters are overexposed. Environment is 1,0 for GI. Or maybe the fault is somewhere else? [image: YFJC_12.jpg]

@filipebonito said: hello, i would like to know if there is a way to save the camera focus point for each scene so when render multiple scenes using depth of field, each frame has the correct focus point? i tried to update each scene with different focus points, in RT render the focus points are saved, but when i use the final render, the focus points don't move... what can i do? thanks filipe bonito Alas, no. Camera settings do not change between scenes. I think that is a highly requested feature for the next version. currently you need to change it manually between renders.
