RPC Proxies

[Ana Lyubenova]

Yey! Well done!

[agrieveson]

Awesome. It's a little more work but the outcome is much better. Thank you!

Kraig, What material did you use for the grass here? Or is it a very dense number of proxies?

[MkX]

I think He used the Fur option which is coming with 3.60 update.

[Kraig_Cline]

agrieveson, as MkX said. It is the new fur option. Which is amazing, finally being able to produce grass in Revit has been a god send.

[agrieveson]

Kraig, looking at it in more detail I realised that is what you used.

What threw me off was the bit of the ground texture you can see through the fur where it lacks density. At first glance it looked to me like you had managed to achieve some kind of variation/addition of other plant types in foreground with the fur! Just a trick of the eyes it turns out...

[Kraig_Cline]

Yes indeed. I use a seamless grass texture below to give the fur variations in color as well as supplying the base as much depth as possible with a flat image.

Dear everyone, I am new here in the forum, My question on the proxy trees is: how can I keep the correct mapping for the leaves, if they are accurately made material (means a pretty detailed tree leaves with an opaque mask to ensure the right shape and color etc of the leaves, such as the trees made by "speed tree cinema"), the problem comes from the size of the material may different for different single leave....is it possible that this kind of trees be utilized in the vray for revit?

Hi Jim,

I'm trying to understand whether your question is: can we use SpeedTree Cinema objects as proxies in V-Ray for Revit? Or it is related only to proxies mapping?
Please, clarify so that we can assist you.

Dear Ana my question related to the proxy mapping only, the situation that every leaf is mapped with a dedicated material which is masked by opaque map to ensure the shape of the leaves. In this case the size for the leaf material(actually the mapping size) may be various and the mapping shape and direction may also be various. If the leaf’s size is not matching the shape of the leaf in the model, the leaf will disappear, since there is a mask in the leaf material, when size is wrong the leaf geometry will get into the transparent part. But when we apply a material to proxy in Vray for revit we need to input a size for the material. So I am curious if there is a way that we can use this kind of proxy in revit?

Hi Jim,

We tested with a tree exported from SpeedTree Cinema. It was exported in .obj format. Then we converted it to .vrmesh using the ply2vrmesh tool (https://docs.chaosgroup.com/display/...%7C+ply2vrmesh)
Then imported the .vrmesh in V-Ray for Revit. The different leaf sizes have different material IDs.
You will have to recreate the materials in the V-Ray Standalone Material Editor and then simply assign them to the slots. That's it.

Let me know if you have any further questions.

Best,
Ana

I would recommend looking at the tree collections over at evermotion. They have some already that are vrmesh files and you just need to create the vray materials based on the textures provided. They seem to work well with the issue you described.

Thanks a lot.
