[Max] I need help! / Re: Cinema 4D ColorMap

Hi. I don't use C4D, so I might be way off. But anyway... what happens if you set Gamma to 2.2 instead of 1?

+1000 for Real World Scale option, coupled with correct scaled procedurally dependent on the units used.

Tried your free material samples, and I think you did a realy good job there. But the lack of Real World Scale means that one have to do his own corrected versions of your materials for use in most Arch Viz jobs.

Not as efficient as it could be ;)

Keep up the good work

[Max] I need help! / Re: DOF in new version

« on: 2015-03-02, 23:44:24 »

Hi. If you're using v1 and follows the description from Rommulus last post, then it should show in the IR. Don't use Max's DOF and f-stop settings in the Camera. Use the settings in the Render Setup, scene tab (or use a Corona CamMod).

Hope it helps

[Max] I need help! / Re: Purple tips of tress with HDR Skies

« on: 2015-03-02, 23:29:25 »

Hi. It really depends on the quality of your HDRI background. Personally I mostly use either Sky & Sun or HDRI. If I occasionally use HDRI + Sun, then the sun will typically be set rather low (like 0.01 i.e.)

To change the exposure/strength of the HDRI background without changing the overall EV there are several options:
1) Change the exposure during import
2) Put the HDRI into a ColorCorrection map
3) Change the settings in the bitmap "Output" rollout (i.e. change the output value - like in mr)

If you want the HDRI not to be affected by the overall exposure, then do like DeadClown suggested: put it in a CoronaOutput map and uncheck (default) "Affected by color mapping". My personal experience with this method is, that it can cause artifacts in opacity materials like the one you're having, if the mask isn't 100% black & white.

Hope it helps

I honestly think you're making your life much more difficult by using Max's exposure control. Use the exposure in Corona VFB or render setup - it's interactive, so you can see your changes while rendering.

Regarding your alpha channel/cut out mask, then don't convert the colored image itself in PS, but use the alpha channel to make a black & white mask image.

NB - "Premultiplied Alpha" is part of Max standard, and therefore it has been present in mr for ages. Nothing related to Corona

Hope it helps

[Max] I need help! / Re: difference in renders from v.1 and A7.2

« on: 2015-03-01, 21:59:07 »

Hi. Seems that your Max behaves different than it should. So just to be sure:

1) Have you tried to save the file with gamma/lut enabled (2.2), close file, close Max, restart Max and reload the file?

2) Have you installed the latest SP for v2014?

I'm running Corona v1.001 in demo mode on MaxDesign 2014 SP5, and haven't had this problem (yet).

What's wrong?

[Max] Resolved Bugs / Re: IR + bitmap map (RGB level) crash

« on: 2015-02-19, 02:20:04 »

Hi. I'm still using A6, but I had a similar experience the other day with a file that crashed every time I used the VFB or the material editor. Finally I got it to work by simply making a renamed copy of the file.

Have you tested that it isn't caused by a corrupted file, or a HD problem?

Hi. These articles from the Area explains the problem/solution:

Seems like it's a Windows limitation not handled efficient by Max ATM.

[Max] Resolved Feature Requests / Re: Renaming CoronaAO map

« on: 2015-02-11, 21:48:07 »

Yes, AFAIK you missed something : )

AO is not about light (direct/indirect). AO is basically about distance to other surfaces. In that way Corona AO acts like mr AO.

That depends... If you want to use IBL with mr, then that's the way to do it (old or not). Works great BTW.

[Max] Resolved Bugs / Re: Scene Explorer - Light Explorer (Corona Light Intensitys are very weird numbers)

« on: 2015-02-09, 02:40:22 »

Hi. AFAIK the lightlister in Max has never worked with Corona lights. That probably why a dedicated lightlister for Corona was done. As I understand it, there are no plans to make the lightlister in Max compatible with Corona due to some technical limitations - but Keymaster knows more about that than I.

Hi. Can confirm this problem in A6. Only solution I have found so far, is to move them apart (just like you show).

Hi Cyrus3v. The map actually shows 15 slot - starting with slot 0 (instead of 1). So 14 connecting to slot 15 is correct, but not logical.

[Max] General Discussion / Re: Black highlights with low refl. glossiness value behind glass

« on: 2015-02-03, 11:56:25 »

Hi. Have experienced similar problems with wood and glass, but found out what I was doing wrong. Maybe you got the same problems.

1) The black parts of the wood in pic. 1, could be caused by the glass and wood intersecting or being coplannar. If that's the case, try to separate them with a little amount (in my case 0.1 - 0.2 millimeter was enough).

2) The noise (or some of it) in the other renders, could be caused (or enhanced) by to high bump values in the wood material. Corona is extremely "bump-sensitive", especially regarding reflections.

3) If you use "Thin" glass, you should use a plane - not a box.

Hope it helps
