Solved with Redshift object applied to a plane on the floor! However the settings are tricky! You have to spend a while clicking around. Have a nice day!

Dear Sassi, Everything works fine but the Shadowcatcher: https://www.youtube.com/watch?v=MXFYZhfI5yc Where is this in Redshift? It worked so easy before Thanks

By the way, I managed to get tracked an Iphone 16 pro Prores footage. Working on the scene. I'll let you know

I'll try Thanks!

Thanks Dr.Sassi! I'm going to make several tests. Also will use a Fx3

Hi Dr.Sassi! What do you think of this tutorial? That's what I plan to do with a footage very similar
https://www.youtube.com/watch?v=K0uD1BpwVHE Is there something missing?

Hi Dr.Sassi! Thanks for your reply. I never compose the footage with 3D in C4D, that has to be made in Davinci, Motion, AE, Nuke, etc But I like to have a rough quick view in C4D I'm sorry to make you write. The problem with text is that the interface of C4D, and ways to do things, change a lot, so it's difficult to find the tool in the right menu. And C4D has infinite menus. It will be good if you point me to a tutorial. There are too many and with different opinions, so at the end you waste a lot of time in youtube until you find the right one. And may be outdated! Regards

Hi DrSassi! I already did the tracking and is ok. I used to do in past versions. However I’m new to redshift, so I need to check some frames how the 3D object looks on the background first, and how to render the shadow. Redshift seems to have changed many things

Morning Dr.Sassi! I'm working with a basic camera tracking scene. Things have changed as I don't see the Background object.I'm new with Redshift! How do I see a test render of the 3D object with the footage background? Besides, how do I have the shadows in the alpha channel with some transparency?
I can't enclose the scene as it is too large. Is just a clip of 15 seconds walking on a road, taken with an iphone, and stopping in front of a clear space in the road, where a 3D cube will be. Very basic. Thanks for your help!

Hi Dr:Sassi!
I checked the settings of 3 point lighting scene enclosed and realised I was using the Area light to 100 units! I thought it was percentage! I reduced the intensity of the light to 5 units and render is made in minutes! I haven't used Redshift before, so I was used to the Standard & Physical render. So my mistake! Anyway, when you have time and tell me how can I get the fastest render with a Macbookpro 16" M2MAX with 64 GB RAM, I'll appreciate that very much!
