Continuing image file saving

Dchimenti — Wed, 07 Aug 2024 20:48:58 GMT

Hello, all.

I'm continuing to have image file saving problems with Max 2025. Problems that never existed in 2024,

First, while saving a PNG, I was not getting an alpha saved with it. Despite having the "alpha channel" box checked.

That problem continues to sit on the boards unsolved.

Now I'm simply trying to save a JPG file from the Active Shade screen and am getting differing results. What's being seen on screen is not being saved into the JPG.

I've attached the resulting JPG save, as well as a screen grab of what the active shade window is actually showing.

Thank you.

I haven't tested the PNG issue you mention but I'll try to see if I have the same problems.

As to the color, I've found the new OCIO option for Color Management problematic. I don't collaborate and share files with anyone so I just need for my files to look right. I don't use the OCIO color modes at all and use the Gamma Workflow and I don't have problems. I know that's "old school" but I don't have time to figure out all of the Color Mangement options with the new OCIO features that studios use.

So, give Gamma Workflow a try or spend a week trying to figure out how OCIO works and what to do when you open it in Photoshop or UE and the colors are just all wrong...lol.... 🙂

I tested exporting PNG renders from the Max Common Settings and it worked perfectly. I attached a shot showing Photoshop, Max and the V-Ray render window with 'Alpha' selected. What Render Engine are you using and could you have accidentally turned off a setting that it causing the problem?

I went ahead and tested Arnold and no problems either.

OK!!!!!

It turns out it was the #%@%ing default OCIO setting. Switched it to GAMA and I'm now getting alpha with my PNG sequence. Unbelievable that I lost all those basic hours banging my head against the wall because Autodesk decided to flip a new switch by default.

You marked the wrong post as the solution as you just did what I had suggested. Users will figure it out and benefit from it regardless. Glad you are going again.

If OCIO indeed breaks the alpha channel in PNGs this should be reported as a bug.

Can anyone reproduce this?

Can you explain the precice steps you are taking that lead to a broken alpha channel in PNGs? That way, people can do exactly what you are doing and see if they have the same issue.

If so, anyone who has the issue should report it as a bug. The more reports, the more attention it will get.
