Hi,
I have observed two scenarios not being accepted.
In the render space, when I render the object using the in-canvas render it doesn't render the changes I made to the material in the model space. Example - I select an applicable material in the model space that has an applicable appearance and apply it to an object/component etc. When I change to the render space and render, it does not render the updated material. The only way I have found to update the material appearance is to open the appearance dialog in the render space and make a very slight tweak to the material (I don't think there is anything specific that needs to be changed). In my last project I had about 10 different materials and I had to do this for each material which was very frustrating.
In the model space I have the appearance set to a default grey. It stays as grey even when I define an object with a material (and associated appearance). When I switch to the render workspace, make some tweaks as above and then change back to the model space only then does the material display correctly in the model space.
Thanks,
Joe
