Re: New V-Ray (1.48.66) won’t render
@DKENDIG - No unfortunately in this case the force sync did not fix the issue. Thank you for explaining the regenerate. I re-imported the materials to their correct assignments and it is fine.
Re: New V-Ray (1.48.66) won’t render
Odd… and you said that this is still the case even after using the Force Sync for All Materials tool in the debug menu? Where did this tree come from? Is it on 3D Warehouse? Would it be possible to send us the offending tree so we can figure out what makes it so special? btw, “use color for transparency” will make your diffuse layer ignore anything you have set for a transparency texture. Instead it will use the alpha of the image that is being used for the diffuse color texture. Just wanted to be clear everyone knew what that option does.
Yes, even pressing the “Force sync” option, still no sign of render.
Maybe you can try downloading the tree yourself and trying to render in a large scene with at least 15 - 20 of those, and tell to us if you could render or not. It’s available through this link:

Re: New V-Ray (1.48.66) won’t render
I just downloaded the model and started trying to render it. I’m just doing one tree for now. It appears to render VERY slowly once I enable transparency. Just to simplify things a bit, I went in to the GI render options and set it to only use DMC for the first pass, and then nothing for the second pass. Now the tree seems to render fine. Then I set the GI options back to defaults so I was using Irradiance Map and DMC again. I went in to the Irradiance Map options and I set the Min Rate to -4 and the Max Rate to -2. Now I can see it start to render the tree a lot sooner, but it still takes a long time to render. Still don’t know what to say about this issue really. All I can say safely is that the tree model you linked me to can in fact render in our plugin without needing to do anything special, it just takes forever. There might be a setting that needs to be changed somewhere, but that’s not really my area of expertise. This still needs to be tracked down further. Hopefully someone can get to the bottom of this by next week.
Re: New V-Ray (1.48.66) won’t render
Devin, I also noticed that the tree renders very slowly with the default visopt which came along with 1.48.66.. maybe something regarding the DMC or another setting at the options.
But when I change to my personal exterior visopt (Primary: IR - Secondary: LC) it renders much more faster. The only thing now that needs to be fixed or discovered is that question regarding the use of many of those trees in a large scene.
Re: New V-Ray (1.48.66) won’t render
The DMC is a more precise method that Light Cache and take more time to calculate than Light CXache as well. So, the DMC always going to take more time than Light Cache. The main issue here is the transparency rays trace and the option that controls that is on Global Switches, “Max Transparency level and Cut off” If you reduce those value, for example, the cutoff to .5 and the Max Transparency level to 10, the render is a lot faster. But the default value sould be ok and faster. In the build 1.05.30 with exactly the save value of our new default value (1.48.66) the render is faster. So I don’t think that the default value is the issue here, or the DMC, Light Cache. We have to find some weird thing that is causing this issue.
The problem by turning down the Max Transparency Level and the cutoff id that you could limit the transparency for glass, and that is not good to have a very nice and realistic glass stuff.

I just used that tree in a render - using IR+LC. Did not notice any slowdowns with it.
Re: New V-Ray (1.48.66) won’t render
I dont know if this is useful information or not, but I had a scene a few months back with version 1.05 that had 20-30 of those exact trees in and it would never render at all, it would just crash with memory issues. In the end I created different camera scenes with just the trees in that scene visible to the camera and all others frozen off. My point being that even with 3 or 4, these trees take an absolute age to render, and I have a pretty high spec machine. I was willing to take the time sacrifice because they seem to look so good.
I havent had chance to try that scene in 1.48 but I’m guessing it would still have the same issues as what you are describing Dkendig. Those trees are a sketchup killer, I dont think its a Vray issue.
Re: New V-Ray (1.48.66) won’t render
I don’t know. I’m struggling with a model that rendered without trouble in ‘old’ Vray but won’t render in Vray 1.48.66 - now Vray and SU simply shut down altogether. The problems I have seem very similar to those described by Shinkakashi. But a scene with five of these trees (very nice ones I should say) rendered just fine.
