To capture the remaining geometry, increase the "Ray Distance" value under the "Bake" panel (it's located just under the "Selected to Active" checkbox). However, you will notice that only some of the geometry has been baked to the plane, which I think is what's happening in your first screenshot. Now, in the UV image editor pane, you should see the geometry of your scene baked onto the texture. Next, under the Render tab, scroll down to the Bake panel, change the Bake type to "Diffuse Color", check "Selected to Active", and set the margin to 0px, and click "Bake": Make sure you select the large plane last, as this will make it the active object in the scene (indicated by the brighter shader of orange): In the 3D viewport, select all the smaller planes, and then select the large plane.
Next, tab out of edit mode, and back into object mode. Next, in the materials tab, create a new material, and under the "Surface" panel, click the little dot to the right of the "Color" widget, and select "Image Texture":Ĭlick the dropdown to the left of the "Open" button, and select the image that you created in the UV image editor. In the UV image editor, select "New" from the toolbar along the bottom, and create a new image: Right click on the edge of the 3D viewport, select "Split area", and in the new area that appears, switch to the UV image editor. Select the large plane, tab into edit mode, select all vertices, press U, and then select "Unwrap" It's a crude attempt at recreating your scene, but essentially, we have a large plane (which we want to bake our geometry to), and a number of smaller planes (which represents the geometry you want to bake) I guess this is a bug - and a waist of a day.Īnother bake attempt following fergal's instructions Furthermore a diffuse bake shouldn't be affected at all. Still I don't have no clue why those values are just cut-out of all baked maps - a normal bake should contain the negative values and it should work correctly when used as normal map. On a regular image values below 0 are displayed as black. That may not even be an error, still I don't really know how to compensate for that.ĪNOTHER UPDATE: After doing some research I found out that the black parts in the 3rd image are indeed no error - Normals go on the red, green and blue channel from -1 to 1. Its the normals facing the camera directly, become black. UPDATE: I think I got closer to the actual problem - see 3rd image please.
I need to bake because I need other channels too, like normals, AO etc. Is it even possible to bake geometry to a flat surface? I tried all options, like a cage, moving the bake target around (in front of the object, behind, in centre) etc. However, parts are just missing on the bake. I try baking foliage to a flat surface as seen in a 3D Max tutorial.
