im currently making an underwater scene which has caustic lighting in it, so i prepare the objects (lamp, 2 planes, one with ocean modifier) and give movie texture to the lamp and... it doesnt work.

i know how to do this in blender render, in fact it just works like the same as i did in cycles render : give a movie texture to the spot lamp and it works. but it looks like cycles doesnt work the same as blender render.

here's what it looks like when i give texture to spot lamp in cycles

i've connected a texture coordinate : reflection node to the movie texture (edited : it works and it animated, i tried rendering it out to see the light and it animated)

  • $\begingroup$ In the Image Texture Properties rollout the source field is empty and it writes that it can't load the file. Did you make sure to load in the movie in Blender properly ? Also use some vector input for the movie. $\endgroup$ – Mr Zak Feb 5 '17 at 10:11
  • $\begingroup$ @MrZak thanks for the suggestion, it works after i connected it with vector mapping node, the cycles render cant animate it realtime, but it played when i rendered it out. $\endgroup$ – Jass Kick Feb 5 '17 at 11:08

might not be exactly what you need but could help. The set up is for a videomapping. Create a spot lamp, you might need to crank it up very high (Like VERY high, use filminc blender if needed)Put a plane between the spot lamp and the surface that needs to capture the projection. Nodes for the plane

Nodes for the plane

animate the offset if it is a video file
