[Max] General Discussion / Re: Max extremely slow to close

Awesome this worked for me as well! So strange that I never had this problem until 2024. It removed 15k animation layers it said. But how did those came to be? I ony did 4 very basic camera animations in the scene I had problems with...

I really need to switch to another 3d package...

Oke yes I got this far, but where is my semi transparent alpha channel? I know I can use a mask in corona to single out objects but I need something that allows for half transparant pixels that give me the same result in photoshop as it does in the VFB.

Check the alpha channel of the render you just showed me, I need that map to give me the same results as in photoshop. As or right now it doesn't and frankly this is either a bug of corona has gone down hill since Chaos Group got involved. I'm a bit frustrated that something this simple is so hard to do...

I sometimes use the Opacity setting to get the effect I want. But usually I change the IOR or the reflectiveness. In both cases I get a wrong alpha map.

But as I stated before, even if I save the alpha channel to a file, I get a different image than the VFB shows me. So I think the problem is in the saving.

I need to be able to save an image as a PNG with an alpha channel so that they guy who I send it to can put it in his Powerpoint presentation. The background of that presentation is similar to the background color I set in 3ds max but the brightness or tone can vary a little. In the past this wasn't a problem but now it is. So I shouldn't need photoshop to do anything. The reflections and transparency need to be the same as in my VFB. In my scene I have only my environment as a background.

Hope this is clear :)

Oke so the way I fix it now it saving the alpha separately and adding that as a mask in photoshop. Then I adjust the mask with a Levels adjustment until it looks similar. But I just noticed that I see lose some reflection and can't get it back.

But are extra steps I don't want to have to make so I'm still curious why this is happening and if it will be fixed soon. Maybe I should try to go back to an older version see if this is also happening.

Ah yes I see.

Did you change the teapot to be half transparent later? Because that's also not changing in the renders you did before.

Aren't those black borders from the environment? This looks correct to me.

I just discovered that when I save the alpha channel as a separate jpg (also tried tiff) the output image is a lot different than what I see in my VFB. So that's very strange, the saved image should be at least the same as what I see in my VFB.

Yes, partly. The bg color cannot change too much obviously because then it would be visible in the alpha, there is no way around that as the semitransparant pixels are set to certain color. I know the background color of the presentation but there is a slight gradient so to do this correctly I need an alpha channel. At the moment the alpha channel just isn't correct because the result in photoshop is not the same as in the VFB, which should be the case according to an old video about compositing on the Corona youtube channel. Like I said, this used to work in older versions of corona. FYI I'm using the Legacy material, I'll try if the new material has the same error but this should work either way.

I guess it's harder to do with glass boxes because it's much easier to spot the errors. With a more complex object it's also wrong be harder to see. But still the difference is huge, VFB vs Photoshop.

Can you tell me how Mask Propagation works for you? I enabled it in the material but don't see any difference in the Cmasking element. Cmasking element only gives opaque masks as for as I know.

I'm on Max

The problem persists with a black background and to my suprised I actually have the problem with a normal basic glass shader. When saving to a PNG the alpha channel is not correct.

The last time I worked with Corona was with version 6 I think, I don't think this was an issue at that time.

Hello,

I'm having a bit of a problem. When I render a glass material with 0.5 opacity value the alpha channel is not the same when saved to a PNG. It's much less visible. Doing the reflections in post is a pain in the a** because of the bloom&glare that's in the image.

Example:


How can I fix this?

Second one +1.000.000! This has been broken for years and it would be so useful. But I guess it's an autodesk thing

Please make this happen!

I'm sooooo done with 3ds max and all it's flaws and crashes... When corona is available for blender like it is in Max, I'm switching!

So +1000

Very nice, I like the style!

The book models you use are very detailed, do you mind sharing where you got them?
