I'm currently in the process of evaluating realtime renderer for our companies' visualisation pipeline. Right now I'm testing TM and joined the webinar today, unfortunately I was unable to give direct feedback, since I don't have a Youtube account.
I would like to give some feedback and ask some questions here, based on my experience during the trial.
We work with Revit 2019, therefore everything import related refers to Revit.
Don't get me wrong, TM is awesome and has a lot of great features, but pardon me if I wont include that in my list.
Probably some points I just don't understand correctly, I'm happy for any explanation.
- -A written documentation with some detailed explanation would be helpful
-Searching through a list of 100+ short youtube videos is a bit cumbersome (aren't they a pain to maintain anyway?)
I understand that the interface was meant to be user-friendly and easy to learn, it probably works well for a touch-screen, but not for mouse and keyboard users.
- -GUI elemets (Icon, text...), while looking great, take way too much space
-too many nested options require too many clicks
-numeric inputs of values (e.g.material reflection) require to press [Esc] for confirmation, if you press [Enter] you need to press 2x[Esc] to exit the input. This is quite confusing, cause usually you cancel inputs with [Esc] and confirm with [Enter].
-some menu names and sorting are confusing, like "Measure" inside "Urban".
An optional less nested compact GUI would be great.
- Unfortunately UE4 doesn't support IBL at the moment and therefore I don't expect you have any plan to implement that by yourself in TM. It would be helpful though to have an easy solution to switch the environment map.
- -IES lights are imported as geometry, the light cone is actually converted into a mesh which cannot be replaced due to the write protection of the import. Is there a best practice solution to how to deal with lights?
-Decals are currently not imported
-Objects that don't have a material with a diffuse map applied receive a UV layout of 1 square feet per UV, this probably comes from Revit internal imperial system. To achieve a consistent texel density and fit to metric system, we have the scale the textures by 3.28 (or its factor). Would it be possible to rescale during import process?
-From performance point of view, are there any recommendations as to when combine meshes by material or family or to keep separate?
- -If checked in the options, how does the replacement of Revit materials with TM materials actually work?
-Is there any way to match a Revit material by a specific TM material? Some kind of name list.
-New Revit PBR materials are currently not converted, though they mostly match the UE standards, are there any plans to implement a conversion in the future?
-How can we change/modify grass materials?
-Material reflection (should be called roughness since you use roughness maps as input)
-Roughness maps seem to be read in srgb instead of linear colour space, therefore roughness looks a bit off when set to 50%
-Is there a threshold setting for the slope material of terrains?
Would be happy to hear from you and other users, maybe the majority might even disagree to some points.
