Is there a way to instance the Corona mapping randomizer but use different maps for each instance of it? Its a pain to have to adjust it for each map  of a material.
 Thanks for any help

[Max] Bug Reporting / Cryptomatte and DR

« on: 2023-08-01, 16:40:40 »

We have been having this issue with rendering Cryptomattes using Deadline's Distributed rendering. All of our other passes render out fine. While the render is going the crytomatte looks the way it should, but as soon as its done and its going through the denoise phase, the CM pass looks like a bunch of dropped buckets. We are trying to determine is this is a deadline or Corona issue. I feel like if it was Deadline, then all the passes would look like the attached image.

 Has anyone else had any sort of issues like this?

 Thank you for any help on this.

[Max] Bug Reporting / Corona Decals are affecting lighting

« on: 2023-07-18, 21:07:03 »

I work in product viz and we have a lot of decals we place on certain products. Everything from logos to labels. I have 14 on the one I'm working on now. Our method of working is to put an alpha map of the decal in the opacity slot of a material and use  "From material" on the Corona Decal.

 We have to render these products twice. One with the decals on and one with them off. What I have been noticing is that when I turn the decal layers on, the lighting changes, usually it will brighten the scene.
 
  Has this happened with anyone else? We are using Corona 8 at the moment. I would like to post a scene or screenshots for reference, but unfortunately I can't (NDA)
 Thanks for feedback and or help.

[Max] I need help! / decals showing up in reflect pass

« on: 2023-05-01, 19:53:31 »

I have two decals on the side of this truck, with the exact same settings as the base paint layer. So why is it that the decals show in the reflect pass? Shouldn't the whole side of the truck look the same? I shouldn't be able to see the decals in the reflect.

 I'm using the Corona decals for this.

 Thank you for any help.

[Max] I need help! / Using decals on glass

« on: 2022-11-07, 22:47:01 »

Does anyone have any work arounds to applying decals on curved double sided glass. Corona decal wont work because it shows on the back side of the glass because of how tight the curve is. I tried doing a poly select with a corona layered material, but then is gives me this really ugly stretched part of the decal on polys I dont even have selected. I also tried close the polies and just applying the decal to that, but since this is only a mask with a white material, you can tell at certain angles. Been dealing with this for a few years now, was just curious if I'm missing something.

 Thanks for any help.

[Max] I need help! / Lost my license for no apparent reason

« on: 2022-11-05, 22:24:35 »

I know that this will have to be handled by support at Chaos. I'm just curious if it happened to anyone else.

 Last night for reason at all. I lost my Corona license. When I login to Chaos, it shows that Corona is an active product and everything is paid up to date, but when i go to the license page. It says I have no active license. Which really sucks, because i seriously doubt I wont hear from support till Monday, but I have work to do now and can't. Has this happened to anyone else?

[Max] I need help! / Render elements are blown out when using Interactive lightMix

« on: 2022-02-13, 23:24:06 »

When I adjust my lights using the light mix, the changes dont reflect my render elements, like volumetrics, BloomGlare, reflect and refract are all overexposed/blown out. Is there a way to fix this?

 Thank you

[Max] I need help! / Roof Material not rendering. only showing unlying roof support

« on: 2021-09-30, 17:48:47 »

I have a separate object sitting on top of the roof support, but for some reason I cant get it to render. You can see in the side view it is actually sitting on top and not underneath. I'm also including the max file for anyone to hopefully figure this out.  you cann in the one render how high I have to raise it before it will actually show up.

 Thanks for any help
