Corona Camera Mod always update the rt render changing the parameters.
I think it's wrong.

I have to apply an edit poly modifier.


Resolved feature requests / set rt resolution

Fixed and variable resolution. We can't set a precise resolution during the rt-render.


I need help / DR render problems
« on: 2015-03-01, 18:25:44 »
I'm testing the latest 1.0 Corona demo
I installed it on two workstations both with 3ds Max 2014
I authorized the demo on both. I started a render locally and it was fine.
I installed DrServer on both machines (to be sure)
I din't installed the LicenseServer because I'm running the demo on both machines.

I started DrServer on the second workstation.
I pressed search LAN button, Max found the right DR machine ip.
DrServer accepted the connection on ports UDP19666, TCP 19668, loopback TCP19667
Max started to render only locally, no pass was passed from the DR Node.

This is the log:

I need help / help with proxies!
« on: 2015-03-01, 16:48:14 »
Hi all,
I'm testing the new Corona 1.001
I did a clean installation deleting the previous version (alpha 6) within the 1.0 installer.
I opened an old scene with a lot of vegetation created with Forest Pack Pro.
Last year I created all my Corona proxies via the Vrayproxy converter script.
Now in all my scenes all proxies are disappeared!
What can I do?

selecting a CoronaProxy I read: (ERROR) Cannot parse file 'my path...\myproxy.cbin'

It seems that Corona can't read the old cbin file structure

please help.


Resolved bugs / interactive PT->VCM crash
« on: 2015-02-26, 20:03:01 »

simple to reproduce:

one plane + one teapot
white GI
perspective (no camera)
interactive render on
switch in realtime from pathtracing to bidir/vcm


Resolved bugs / two issues
« on: 2014-04-25, 11:05:11 »
#1 xform has no effects on Corona light. Sometime I use it to re-orient multiple instances of lights without open all groups

#2 gradient ramp has no effect on self-illumination texture slot,. It's ok for Corona light material.

Resolved bugs / ray bias refraction bug
« on: 2014-04-20, 16:17:42 »
I've encountered an issue in refractions. (Alpha 6 14-04-2014 daily - Max2014)
I have a large model in Max modeled in meters (modeled with Autocad + Rhino in meters)
I created some thin glass panels 0,01-0,02 meters thick (1-2cm.)
On these thin glass panels refractions and absorptions are wrong rendered if the thickness is 0,01 or 0,02 meters.
If I change the thickness to 0,03 these panels are rendered good.
The absorption creates a strange effect on these panels, a sort of circular area in front of the camera (also on the left-right side)
Soon I will post some screenshots.


General Discussion / too much fast
« on: 2014-04-07, 18:48:05 »
Why Corona is so fast?

I'm just rendering an huge arch viz scene at 4K with 17M of polygons, forest pack, displacements, many layers of glass, tons of ies lamps.

after 20 minutes the image is acceptable...

impossible to achieve these results with whatever rendering engine on earth.

I think that Corona exceeded the speed limit and it's coded with alien technology...:)


General Discussion / how to in A6?
« on: 2014-04-07, 16:30:00 »
Corona A6 is great...

but I would like to know how:

having in a scene different cameras with their own exposure values, white balance, contrast, clamping.
how adjust the displacement value +/- per object
how to blend a Corona light material with a Corona standard material using a mask


when the RT will be enabled?
when the dispersion will be available? I don't want to use Keyshot anymore.


I tested my heavy and huge scene with tons of trees generated by Forest Pack Pro (latest release 4.16)
With FEB23 the scene is rendered. With releases FEB26 to the latest the Building acceleration structure pass hangs. Timers count, impossible to stop the process, I have to kill Max.

Resolved feature requests / Corona light lister

sometime very useful.

Resolved bugs / luminaire assembly issue
« on: 2014-02-23, 23:01:31 »
the luminaire assembly has a wrong bounding box (ies light + circle mesh)

Resolved feature requests / ies shape visible emitter
« on: 2014-02-23, 21:15:53 »
would be nice to have an option to render the visible ies shape: rectangular, circular


Resolved bugs / ies button
« on: 2014-02-23, 20:51:08 »
pressing the ies button to load the ies profile it doesn't remember the latest ies path.

I don't know if it's fixed in the daily build.
