I have discovered hrd images to light my scenes for me!!!
Render time was 3min 24 secs
I have tried so many times to get this to work and I finally did.
C&C much appreciated :smiley:

I am having a hard time getting caustics. I guess I dont know how to do it using HDRI.

Looks quite nice (a little too simple though). Table texture doesn’t look as ‘sharp’ as your metal object.

Your object doesn’t need caustics. Only with glass objects and objects like this:

Other examples of caustics:

afaik, you need a photon lamp to generate caustics. it won’t affect “the rest” of the lighting in the scene, it’s just adding the caustics effect.

I used photon lamps before, but I am having trouble knowing where to place it to get caustics to bounce of the inside of the mouthpiece.
I see what you mean about it being simple. I was thinking about adding a sheet of music in there, but I am having trouble getting realistic materials.

Here is a close up shot of the mouth piece
Here’s an update. Let me know if you see anything that can be done better.

Thanks for all your help with figuring out the caustics

The sheet music seems to be a bit transparent?

clap! clap! I like it very much, no crits now.

Very good! Are you a tuba player, or is it for trombone?

Only thing I can think of is rumple the edge of the paper a bit more - it looks too old to be so pristine.

Trombone obviously sheesh :wink: I tried rumpling it, but I wasnt very succesful. All I could do was curl the edge
