Alpha channel cast shadows

Hello everyone, I’m trying to do an animation with drawings from Krita.

Add plans in the scene with ADD> MESH> Images as Planes, with these settings


and this is the result of the screen nodes.


The problem is that in the process of rendering I get a shadow specified by the plan, not the texture


What am I doing wrong?

You can help me?

THANK YOU

You didn’t include the image you imported so no, can’t help.

ensure that the transparent node is set to RGB 1:1:1 (i.e. full white). Other than that there is not a lot we can do without the images and/or blend file.

This is the file png


Thanks

This image has no alpha channel. it is an 8-bit grayscale image with just B+W color data
You need to erase the Black sections

It’s a jpeg which does not contain alpha, you need .png with alpha:

This is you bike as a png with alpha:


which looks like this in blender with your nodes

@Photox - haha, you beat me to it, i was just about to upload an edited .png until i saw your post :slight_smile:

sorry, but the picture I uploaded is a png
attach image preview


I do not know why it has become jpg.


this is the screenshot GIMP


this is the file png exported gimp


The image itself is fine


So there must be a problem in the scene setup or settings then.

You have ambient occlusion enabled in world properties, that’s the most likely culprit.
