Title: Frontal projection scene environement
Post by: CBAS VISUAL on 2017-02-21, 11:39:44

hi guys,
someone know how i can put a picture in frontal projection in direct visibilty override. For landscape integration ?

I would like something like that, a slot in scene envirronement, u put ur picture and chose ur projection.
The background will be ur picture, and if u change Ev, compression etc, the changes would only affect ur model, not  the background.

Today i use this technique :
Plan + material with my background picture in frontal projection + corona tag. But i cant explude the plan from alpha and shadows  ...

Thanks guys :)

Hi!

The frontal projection for enviornment overrides is supported now, however it does not work the way it should (this is a bug that we should fix...). As for the exclusion of the image from tone mapping, you can use the Corona Output filter shader for this. There is a checkbox that allows you to exclude the map from the tone mapping operations (see the picture). The downside is that if you change the tonemapping values, you'll have to re-render the picture (as stated by the warning note in the dialog)
