Create HDRI from max scene

[Gander0]

Hi folks,

 

I think the title explains what im after, but does anyone know how to or where i might be able to find information on how to save out an hdri spherical environment from a max scene?

 

Many thanks

You could look into the 'panorama exporter' tool in the max help files. Or if you're using vray then you can also do it by setting up a standard cam then changing the camera settings in the render dialogue rollout to 'spherical', over-ride FOV to 360 and make sure your image size has an aspect ratio of 2.0 i.e. 3000*1500px or similar. Then save your image as either .hdr or .exr and make sure your output gamma is 1.0.

 

Quite a useful technique to know. I recently used it on a job when the architect told me at the last minute to add pendant light fittings to an atrium space I had already rendered. I didn't want to have to re-render the whole image so I just rendered off a quick 360 degree hdr at 360*180px then used that as the environment to render out my light fittings.

Thats great, thanks Stef,

 

I haven't got anything specific i need this for at the moment but there are plenty of applications where I can see it would be useful.

 

Will have a look into your suggestions.
