Blenderproc: How to render Replica images in 32bits HDR (.exr or .hdr) ?

[elientumba2019]

Hello.

1. Is is possible to render in HDR using the replica data set ? Replica comes with HDR texture.
2. How do i render using an Equirectangular camera ? (to render panoramas)

Hey.

1. In the moment this is not possible, we already tried to integrate this HDR textures in blender, but had no success so far. We only support the vertex colors. However, if you want to use the Replica dataset with an other dataset always keep in mind that the light and objects are baked in, which means you can't add new objects to the scenes without breaking the realism. I would rather recommend using a simulated dataset like 3D Front. We provide a loader for that, too.

2. Yes, this is possible, but we don't provide a config value for that, yet.

So, checkout this post, which describes how to render with a Equirectangular camera:

https://blender.stackexchange.com/questions/160590/blender-panoramic-render

You can then checkout, which commands blender uses to change these options, by using the scripting window, which is visible in the lower left corner in this image:

Then you can add the commands which are shown in this lower left window to the camera class and change the settings. I would highly recommend you doing this in the examples/debugging scenario to see the effects directly there.

I hope this answers your question?

Yes. Thank you.

Another question, How do I change the renderer to use? For instance, blender uses cycle by default. I would like to change that to let's say LuxCore. How do I specify that in the .yaml config file? I did not see such an attribute in the documentation.
Thank you

We currently only support Cycles. However, if you would want to switch the renderer you would also need to switch the material handling, if you check out this page: https://wiki.luxcorerender.org/BlendLuxCore_Quick_Start_Guide

They give an explanation on how to do this. But, I do not recommend doing it the benefits are usually really slim, between different renderers. The only exception is usually caustics in glass and if that is not the main focus of your work, you can continue using cycles.

Please for every other unrelated question open new issues, so that other people can more easily find this question.
