I need to access some projects, and this is an old installation of Revit 2013, Octane 2.16 and plugin 2.x (2.3.0.7 ~ 2.16.0.25), and Revit crashes on start, every time the plugin is installed. Octane standalone and Revit without the plugin runs fine. The Revit/plugin combination crashes with every ...

Hi Andre. Thanks for sending through the scene. I loaded it into Revit 2015, and used the displacement map at http://render.otoy.com/forum/viewtopic.php?f=21&t=43025 and it worked fine for me (see below).

Hi Paul,

Regarding the plugin, if I open a 2013 project into Revit 2014 or 2015, will it ...

IMO the better solution is to create many more control points in the topology that you are trying to subd. More control points means more polygons - which will get around the displacement issue you have (assuming this is why you need to subd).

I still can't make it works. Lots of control points ...

I was able to get it working by:

- Set Subdivision level to 1 and subdivision sharpness to 11 and click the reload button for the mesh
- Set the height of the displacement to 0.1

The above only works for Octane Standalone (since the Revit plugin does not provide Subd controls).




Hello Paul ...

Thanks for sending through that scene. You need to ENABLE smoothing for the material used on the column. Pls see FAQ question 1 at http://render.otoy.com/manuals/Revit/?page_id=416 .

Paul

I'm aware of the smooth setting, but sometimes the Revit corrupts the geometry, and even the smooth material ...

Hello Paul,

I'm getting some artifacts from Revit, take a look at these rendered extrusions:

not_smooth_extrusion.jpg not_smooth_extrusion2.jpg

They are just ellipses or circle based extrusions, either Revit components or masses. When I render using raytrace view mode or using the Mental Ray ...

The only subdivision config I found (v2.06) is under the "preferences > geometry import" You need to use 2.16 - since there have been displacement mapping fixes applied after 2.06.

Paul

Thank you Paul,

Now that's beautiful - I got perfect results with 2.16 on my specific scene (another one ...

Still about the second example of the previous post, I found this:

disp_test_floor_and_bp_02_revit.jpg
This is how an elevated (above ground by offset) building pad looks like in Revit

disp_test_floor_and_bp_02a.jpg
and this is how the same scene looks rendered. The way this algorithm works ...

Another findings about the displacement issue, maybe it could help isolate the problem:

disp_test_floor_and_bp_01.jpg
> This picture shows a grass texture with displacement height of 0.0001 applied at a toposurface, a floor object with the same grass material applied, and a building pad with a ...

If you set the subd settings as I documented above in Octane Standalone, you should get acceptable results.

Maybe I'm doing it wrong. The only subdivision config I found (v2.06) is under the "preferences > geometry import", I set both for OBJ and Alembic, the mentioned ...
