Is it possible to script octane renderer to load a .obj file and display the result?

I'd be very interested in knowing if this can be done.

Hi,

Sure that's possible. For example with this script:

Code: Select all

-- create mesh node and load obj file
mesh = octane.node.create{ type = octane.NT_GEO_MESH, name = "loaded mesh" }
mesh:setAttribute(octane.A_FILENAME, "/home/thomas/Documents/obj-files/cube.obj")

-- create render target and connect with mesh
rt = octane.node.create{ type = octane.NT_RENDERTARGET, name = "OBJ render" }
rt:connectTo(octane.P_MESH, mesh)

-- render
octane.render.start{ renderTargetNode = rt }


cheers,
Thomas

Cool, thanks!

Just to know: is it also possible to "move the camera away"? I can render my sample obj cube but it's too close to the camera.
I'm a newbie so I'm not sure how this can be accomplished. I tried searching for "Scale of view" in the scripting LUA API but couldn't find anything

Thomas, can you make it recursive so that it will load the entire content of the specified folder?

This has a lot of potential...
I could not Lua my way out of a wet paper bag.... but seeing this makes me ask...

Is it possible set up a Lua script to load a series of sequentially named OBJs and shatter nodes so that they replace the obj/scatter node currently loaded called mesh_xxxx.01/ scatterxxxx.01 etc so that if

xxx.01 is all rigged up to a render node set to 5000 samples

That it renders out the image saves it with a sequential name and loads the next OBJ/scatter and rinse and repeat???

I have a bunch of scatter nodes that change over time and describe the location of an OBJ that slightly morphs over time but has the same number and named materials. I could load and replace each one and save the file...

But could lua save me the agony??

Thanks

Peter

Hi Peter,
sure, with Lua you can do what you asking for and much more, like create a specific material and assign it to the mesh or part of it, deeply define the various rt options and so on
I'm a newbie in Lua and basically I cut and paste parts of devs code here and there with lot of tries and errors, but it's quite easy to understand when you dirt your hands with it

Thanks man... I'll give it a shot
