RTTGroup and MaxScript
Hi,
I am tring to make a script that use RenderToTexture.
I muddy when i try to add a rendere elemento to an RttGrop i created:
Example:
-- Create an RTTGroup
RttObj = RTTGroup()
-- Add texture element Complete map
RttObj.AddBakeElement (RttObj.CreateBakeElement "CompleteMap")
The last istruction return true but the textture element list is empty...
Any tips?

Re: RTTGroup and MaxScript
Hi,
It is necessary to use this form:
RttObj.IRTTGroup.AddBakeElement (RttObj.IRTTGroup.CreateBakeElement "CompleteMap")
The node's interface INodeBakeProperties already have a method with the same name (AddBakeElement).
Some time ago I wrote a small example script that show how to use RTTGroup API, will may be useful for you.
This script (RTTExample.ms) outputs to MAXScript Listener window the mesh material IDs channel - primary and assigned by RTTGroup, and the bitmap filenames for bake elements.

Re: RTTGroup and MaxScript
Thank you very much for the answer!!
But i have another strange problem :p
now i do this:
-----
RttObj = RTTGroup()
cm=RttObj.IRTTGroup.CreateBakeElement "CompleteMap";
cm.enabled=true;
cm.targetMapSlotName = "diffuseMap"
RttObj.IRTTGroup.AddBakeElement cm
------
now add the bake element, if i go in tool and start the render it do it...
but it don't assing the diffuse map...
The really strange think is: If i press texture Elements and close the dialog, in the next render it assign the diffuse map...
strange. Any ideas for this?
Thank you again

Re: RTTGroup and MaxScript
To set the "TargetMapSlotName" you should use this:
mat = standardMaterial() -- or other material, for example the material from some node
RttObj.IRTTGroup.SetTargetMapSlot cm mat "Diffuse Color"
for every used material type/class.
Thanks,
Andrzej
