RPC Techniques

[dphorvath]

Hi All,
I currently use ArchVision for inserting RPC's into a revit model and then render the scene in Vray for Revit.
I'm not totally loving Archvision's RPC due to lack of control of how they are viewed in a rendered image (they look too cartoony or fake compared to the building items), unless I make every RPC Custom and create a mild transparency into the image via photoshop before making the RPC. I'm not sure if this is the best way, but I feel there is an easier way to put landscaping and other RPC's into a rendering.
Are there any recommendations or better techniques out there that you can suggest?
I'm putting way too much time into putting rpcs into my revit models to create a building rendering, there must be a better solution, perhaps not which is why I'm posting the question I guess..
Cheers,
Dave

Hi Dave,

You can replace the RPCs with V-Ray proxies. To do so, however, you still need to place RPCs in the model. Then, in the RPC Proxies tab of the V-Ray Asset Browser, you can override them with proxies (.vrmesh). Proxies will boast the realism of the image.
Currently, that is the workflow. If you have any suggestions or recommendations, we will be happy to hear them : )

Best,
Ana

Hi Ana,
I briefly looked into using the proxy method. However i found the process to be extremely time consuming and complicated. Although the vrmesh items may look great, i found too time consuming to then have to assign a material to a leaf, the stem, the bark, another leaf type, etc.... and that is for just one of the 50 or more trees, and then that is just the landscape.
Perhaps there is a tutorial to better teach me the proxy vrmesh process. I am probably making it too complicated. And if there was a library to pull from that would help exponentially.
cheers,
dave

Hi Dave,

Thank you for your feedback! I will send you some resources to learn.
Unfortunately, there is no way to save the materials within the proxy.

Best,
A.

For the materials, does this mean that the 3D texture of say the bark is there, but there is no actual material or colour? If so, all we would need is to specify the shade and we would be good to go, or do we need find a bark and leaf material?

Hi,

The proxy format (.vrmesh) holds info about the geometry + the material IDs of that geometry. You need to create V-Ray materials for, let's say, the bark and the leaves, and to assign them on the material slots which appear in the Asset Browser after a proxy has been assigned.

Wish the vrayproxy vrmat process is a bit more automated. I want to be able to just select the corresponding vrmat material with sub_materials and have it match to the correct one, instead of clicking one-by-one
