Silverwing Quick-Tip: Octane Laser Effects PT1 Light Projection

[@eilonhay4812]

Bro you came at the best timing with this tutorial! I'm making a commercial that needs a laser effect I can't describe how perfect your timing

[@SilverwingVFX]

Ohhh super nice hearing that. Hopefully you can make a really nice laser show for your commercial project with this and next weeks video 🙌 Though maybe I should have mentioned, although it theoretically works to have this show up in a volume, Octane had a big bottleneck when it comes to small bright light sources in volumes, so it will unfortunately render forever in a volume 😇

[@fgarciaish]

the way you broke down the pinhole concept is amazing. thank you as always Raphael!

[@SilverwingVFX]

Oh thank you very much. Great to hear the Explanation worked out great.

[@AlexiEffects]

Ladies and gentlemen, he did it again! Totally going to use this technique. Thank you for all you do.

[@SilverwingVFX]

Ha ha ha, thank you so much. Super glad you liked it and for your kind words. Such comments motivate me a lot 🙌

[@FallEdits]

I wanted to try a sonar scanning effect I saw from a commercial and coincidentally, this tutorial pop-up! Thank you for the in-depth tutorial!

[@SilverwingVFX]

Hey, thank you very much. And you are very welcome. Great to heat that you liked it and that it somewhat gave you and answer for the sonar scanner. I guess you can also use it to visualize sonar 🤔

✳ Came back from vacation - rushing to watch your tuts. great job mate!

[@SilverwingVFX]

Oh nice, thank you very much ✨✳️✨ I was a bit "lazy" and did not produce that many new ones. So you should be through with them rather quickly😇

[@JMach4217]

Another amazing tutorial. This now perfectly explains to me why Octane's process for Gobo lighting ALWAYS results in sharp shadows from that Gobo light source, due to the pinhole light effect. Do you know of another way to do efficient GOBO lighting, but still have the flexibility to control the softness of the shadows independently from the sharpness of the light that is casted? That would be an amazing tutorial :)

[@SilverwingVFX]

Thank you very much for your great comment. I have not thought about gobos, but you are totally right. The only way I can think of getting there is to decouple the gobos from the light and have them on a plane with opacity in front of the light. So the light can be softer and depending on the distance of the gobos, the shadow of those can be shaper. I think there might be a trick and even another tutorial in there. Eventually trying to give gobo texture a virtual depth, not behind the light, but in front of the light.... I's certainly an interesting thought!

[@SOAdbENNY]

Had to try this technique on fog medium, its amazing. Thank you man!

[@SilverwingVFX]

Thank you very much for your comment. I find Octane Volumes in those cases very hard to render (clean up) But great to hear it worked out in your case 🙌

[@蛋蛋-t7t]

Thanks, Now I understand the difference between texture maps and distribution maps in the Octane.

[@SilverwingVFX]

Thank you very much and fantastic to hear that 🙌

[@awolism]

Nice, thanks for clearing up some of the details around projecting lights! I'm doing some gobo related work right now, so this comes in handy. ✳

[@SilverwingVFX]

Oh, thank you, this is super nice to hear. I bet this also works great with gobo related workflows 🙌 And thank you so much for pleasing the algorithm overloads ✨✳️✨

10:47 - I am trying to build a physically accurate projection mapped room for pre visualization, do you know if there is a way to control perspective warp like you would with a real projector hooked up from the ceiling? My octane lights are on the ceiling but content is obviously being warped from the angle of projection

[@NebMotion]

I know you moved the lights back to fix but I ideally need them fitted in a specific place - great tutorial by the way!

[@SilverwingVFX]

Hey there and thank you for your question. If I understand you right you want the projector to be offset from the middle of the projection area like a modern day digital projector, that you can place at your table or your ceiling and still project an un-distorted image? To get there with the shader, set your projection to "Perspective" as suggested in the video. Then what is important to have a non distorted projection on your wall at the end is that your light is left parallel to the wall. Do not angle it. This of course will make half of the projection hit the ceiling. To move the projection down from the ceiling to the wall, add a transform node to the ImageTexture. This allows you to offset the image e.g. down by using the Translation Y "T.Y." value. Congratulations you have made your own lens shift setup for your ceiling projector 📽 Let me know if you got it working 🙌

[@NebMotion]

@@SilverwingVFX it worked! such a simple solution, i cant believe i didn't try that THANK YOU

[@SilverwingVFX]

@@NebMotion Amazing. I'm glad to hear it worked. And I know that feeling. Sometimes the simplest answers are the best 🥳

[@yungbuttermilch]

Großartig, danke! In English, so everyone can profit: Unrelated question: How do you get your default light so small? 2x2 m is for most of my scenes a bit overkill.

[@SilverwingVFX]

Thank you very much. Also in English so must people can profit! Also I totally agree, for the scenes that I usually work with, all the scenes being larger then 1 Meter is overkill! I think the smaller sizes are a side effect of having set the default scene to be interpreted in millimeters. Though in newer C4D versions you can also click on the upper right corner of the attribute manager and create presets for the currently selected object. This includes creating a new "master defaults" when creating the object (I think there is a checkbox in the settings with "save as default" or something along those lines). I did that for some other default objects to make them fit my needs better.
