NOMAD AR drawing issues



we recently started to use the AR feature for client presentations.

works very good in accordance to the tracking, layer classes stuff. good job.


some things are strange.

textures that are seamless sometimes show small gaps in the model and the surface starts flickering

geometry (imported obj file) is rendered in the nomad 3d view without erros, but in the AR mode many faces are destructed.


any hints what is going wrong here or how i can get rid of this?

I have seen this before when you have two (or more) surfaces at exactly the same location. When the render engine runs in some places one surface is the one evaluated to show and at the next point over it could be the other surface that shows.


If you can separate the surface by even a little bit (0.1 mm), then the surface conflict can be resolved.


Not sure if this is the issue in your case, but worth a look.

yes. that is what i first thought on this issue.

the original model came from rhino and was rebuild from scratch in vewctorworks

but the roof is only one extrude and nothing else and the car has been rendered several times in rhino maya and c4d with v-ray and octane.

and there it always looks perfect.
