Hi There!

I am working with blender for 3D Things, and the new Version is able to Render to a File called "OpenEXR"... which is a very cool thing because it´s HDR like and contains Alpha layer and also a Zbuffer.

So my question: Are there plans to support this File Format for CompositeLab? Or other High Dynamic Range files?

Dont worry, we note all (crediblle) ideas such as this. All suggestions are concidered, even though we may not always reply!

The functions in the fxhome products currently do not use the extra information in the OpenEXR format such as the Z-Buffer, or Normals channel.

Can I ask FXhomer18554 and metalfish, what do you require the format for? Is it because after you do some effects/compositing in a fxhome product you then wish to do further work with the video in another 3D program?

The FXhome products do not currently support the rendering of 3D objects. Any 3D stuff composited has already been rendered as some sort of movie file. Compositelab, Effectslab and Visionlab perform filters and effects on 2D video. So you would use FXhome products after you have rendered your 3D stuff, when there is no need for the extra data in the OpenEXR format.

OpenEXR would probably be supported if the functions in the software needed data from the format to render 3D stuff. Such as using lighting models (e.g. phong) to render 3D objects. So maybe OpenEXR will be supported, but only if we produce the tools that need it (if that makes sence).

So the use of FXhome products comes after the 3D stuff in your 'rendering pipeline'.

When you sign up you are given that name automatically, to change it click on the 'User Preferences' at the top of the page when you are signed in. Then click on 'Change Username' on the left.

That user name is a pre-designated nick name, which was automatically generated for you when you created an account with FXhome. You can change your user name by selecting "User Preferences", found at the top of the site when you are logged on, then select "Change Username" (currently the sixth option down).

Note: Every member is allowed to change their user name a total of one time with out being required to expend any force. Any succeeding user name changes will incur a cost of 50 force.

Edit: I see JackPot has already answered. There you have it.

Choose carefully.
Wizard.

Hi!

OpenEXR is not just "extra Information" as e.g. Zbuffer... it would be useful for 2D Compositing Tasks also!

You would be able to use EXR rendered 3D elements in a composite. BEcause EXR is like HDR, you would be able to change brightness or Gamma of the Rendered Layer without ever loose any visual information. If you lighten up a too dark rendered video, you loose quality...perhaps ou have to rerender... thats why i like to render to EXR... One Render and youre done.

By the way.. making a Postwork-DoF with the information of the Zbuffer would be 2D and a great feature... right now because there´s no support for such things i do that in blender nodes...
