A trick I use is to be sure to place each ID material to one of the proxy triangles. This way it is seen as used and will not purge and it also stays along with the component.

Beware that purge plugins will also purge materials that are used as part of a 2-sided material. Chaos recommends using the purge material feature inside the material editor.

I don't have vray or a mac, but one possibility and a bump so others may answer, check that you don't have the face reversed.

prior versions had different or less... or no limitations. It's changed a few times, so it's hard to keep straight in my head. Currently though, yes, there is a watermark, output size cap, and a few other limitations here and there.

Nomer get's into a technique on his website.

Ahh my bad, I meant to type "I have GI and BG switched off and am only using HDRI dome"... I think the bright skies are in some cases the realistic effect with these camera settings... must learn to tweak them better and maybe start experimenting with the Aperture F value.

Thanks again for the tip though, I'm sure if other people are checking in on this thread it could help them also 😄

great, thank you all 😄

Great brushes and tutorial! Thanks valerostudio, with your always good suggestions.
thanks guys!

You would need the create the map to be applied to the sphere and then possibly UVW map it outside of SketchUp, maybe using UVtools and Blender? I dont know. All I know is that mapping a sphere in SU alone is dicey.

Thank you, i tryed that (change the IES file) and I manage to get more or less what I was looking for, I still need lots of practice for that kind of render (Night Scene, or interior). At this moment (same model) i'm having issues with a glass material, i'll upload some pictures to see if i can get some help, again thank you very much

As well as the other suggestions, have you tried increasing the HSph subdivs (under the irradiance map rollout) to something like 80-150 to reduce the blotchiness?

Just tried increasing the HSph subdivs to 150 and it seems to be doing the trick. Thanks for the suggestion.

2.0 bump mapping has improved significantly. I would not use displacement on tiles or bricks. Seems like an incredible waste of render time to me. Try bump, trust me.

First I want to thanks you guys who helped me, you are great!

I used the group function and worked perfectly, so the function on EDIT SU materials...

But still I have one last issue, as you can see on the image there is a fail between my grass and my floor...any hint to help me? Thanks very much!

PS: do you guys think the grass is good looking? I lowered the scale, but its seems...different from a real grass :S

Second Try :)

try contacting support@chaosgroup.com

I also have this question. The old version scene cann't render correctly in 2.0 version. Use "Regenerate all Vray materials" can solve the question, but that would lose old vray materials settings.

Check in Vray options under "Global Switches" to see if override materials is turned on.

I've seen that problem as well. Try using TT Vray Toys plugin. It will initially load SU without Vray, so open your model, go to the plugin and load Vray and Voila you are good to go.

it works! thank you jiminy-billy, it solves my endless problems. haha

check your memory usage. SketchUp is a 32bit process, so if you get close to 4gb of ram being used, you're going to get a crash. One day SketchUp will join the 64bit world, and this won't be a problem. Until then, try to keep RT renders in lower resolutions if you can.
