Question by peter · Jan 04, 2010 at 03:34 AM · shader

Blob shadow with projector does not move

I'm using the blob shadow prefab and it looks to be working, except while projecting the image, it does not move the image.

Example:

I parent the projector to a cube that is moving with constant force. The projector projects onto ground plane, but when it moves, the projected image does not.

Update:

I'm using the transparent/cutout/diffuse shader. I use a png file with alpha channel as texture. The image is a star for test purposes. I see the star projected on a plane. I move the projector, the star does not move. I move the plane, the star image moves with the plane.

I've also used the FX/Projector Multiply from the blob shadow prefab but nothing comes up on the plane.

I have a light in the scene...????

Thx for any tips

I got it to work. I selected the projector/additive shader which I never saw before. I must have missed it. Or, it just magically appeared. Dooh!

But now the texture tiles. How do I make it not repeat?

Thanks for posting the answer you found. As for your new question, it will probably get better attention if you post it as a new separate question. It's doesn't fit under the header "Blob shadow with projector does not move" so it doesn't belong here.

Does the projector GameObject move in the Scene View along with your cube?

If not, I would make sure that the cube is the parent of the projector and not the other way around. Otherwise the projector's transform position won't mirror that of the cube with constant force.

If the projector is moving on the Scene View, but the projected image is static in both the Game and Scene Views, then something screwy is going on...you should be able to see the projected image update its position in both views just by dragging the projector in the scene view, even out of simulation mode.

Projector moves, the image projected does not. In scene view and game view consistently shows this. projector is child of moving cube. I also tried moving projector with rigid body and .js, the result is the same. ???? Thx for comments!

$$anonymous$$ore details would help. Like Noesis said, everything should work. What shader are you using on the Projectors' material?
