I need help / Re: Exposure Value Cant be Clicked

If you are using a physical camera in MAX then you need to disable exposure control for the camera in your environment settings.

General Discussion / Re: Corona To Unreal work flow?
« on: Yesterday at 16:27:50 »
Would be curious about this also. Just started playing around with Unreal and Twinmotion. TM was relatively easier (though no option for MAX import), but materials/displacement and lighting (sun more so) from MAX/Corona to Unreal didn't really work well using Datasmith so far. Plus I don't really have a grasp on the material editor in Unreal, so making tweaks is extremely cumbersome.

I need help / Re: Portals - big difference in lighting
« on: 2019-10-10, 16:30:23 »
Looks better with the portals on to me.

I always did what you suggested cjwidd; set sun to .02 intensity and sky to .15, then fiddled with EV.

Artistic integrity aside, I feel that if sun & sky is already set to real world, then you shouldn't be able to change their values; or rather make it idiot proof/clear that one doesn't need to change their settings otherwise.


Steyin, the difference between parsing times for IR and final renders should definitely not be so big - there is certainly some problem (maybe on our side). If you could provide us the scene so we could have a look at it, it would help us a lot with finding the potential issues.
I uploaded the scene in question. Initial parsing time was around 30 seconds, seems it is due to the Rhino geometry, but switching between viewports IR was ok. Every now and again it slows down a little though. Still, hitting render instead of IR parsing was 4-5 seconds.

Hello Steyin, thank you very much for your feedback. Please could you provide us such scene so we could investigate the cause of this issue?

You can use either our Private Uploader: or you can send it to me as a private message. No uploaded files will be shared with anybody else or used for purposes other than debugging Corona without explicit permission.
I'll try to get you the scene along with a former one with a different Rhino export. The one I'm currently using might be heavier due to the modeling of the import...since its from the city of NY and who knows if they know what they're doing. I finally rendered the scene however for final renders and noticed the parsing times were only a few seconds compared to nearly 20-30 for IR.

I've noticed that as of late, any exports I get from coworkers from Rhino 5 (mainly OBJ) are creating long parsing times and slow IR at the beginning. It seems to balance off after a few mins, but I've never had the issue before. I'm running Max 2017 and Corona 4 HF1.

I need help / Re: Triplanar mapping troubles
« on: 2019-09-27, 16:33:21 »
I don't believe Triplanar is really meant for cube/flat objects...which would mean using it as a study would be null (doesn't work well on walls).

These are great. Love the mood and feel.

Just a little detail, unless there is a Cincinnati outside the US, the power outlets in the bedroom look wrong…
I was about to say the same thing.
Very nice images. Also that stair is against code with no railing.

General Discussion / Re: Project Lavina for Corona?
« on: 2019-09-18, 16:34:03 »
Real time raytracing and such is definitely the future IMO, especially for the arch industry. If you can render on the fly for a client it will be amazing. A coworker showed me Lavina a few months back and we agreed that it would be ideal for any arch office. Same goes with VR/AR + BIM. These things will change the industry in a near revolutionary way; only a matter of time.

Great environment and atmosphere.

I need help / Re: glass thickness
« on: 2019-08-27, 16:39:11 »
I always model windows with glass as it is actually constructed, normally two 1/4" panes with a 1/2" air gap, then use the non thin wall material. In this day and age of processor speed/memory availability and the continuing advancement of render engines I find there is very little to no speed difference between the two methods.

Great to see and glad to help.
