For everyone having trouble importing the color data of the PLYs from scaniverse into TD: Make sure to scan your objects as Mesh not Splats. Only mesh scanned objects will have the rgb channels. ;)

Thanks for this amazing tutorial! For a smooth camera movement, you can first have the camera "look at" the GEO, then create a noise chop with two channels x and y, adjust the period and amplitude, then chop reference the x, y channel to your camera x, y translate and/or rotate, which you can further adjust by adding or multiplying after the reference. Hope this will help :D

secret sauce , same concept is with uv you can create nice water effect on image. instead of add use a displace, no noise threshold but the same over technique with level .03 opacity. i like the way you teach BRAVO!!!

HAVE BEEN LOOKING FOR THIS FOR A LOT! you are amazing keep up your amazing work 💖🧠🌸🌼🌻🌺

[lelaamparo]

Wanted to give a big thanks to you. First TD tutorial that was so clear and beyond helpful!

[superthoughts]

This is great tutorial and I am super grateful. I have to admit the voice makes me and my friends a little uncomfortable. a little gooned out serial killer sounding... but I love it! <3 thank you!

[chengchen-ubzj]

hi, my threshold can't be applied to the whole model, it's not obvious... any solutions? thank you so much!😭

[Mindspiritdesign]

From my experience, camera blend technique works best as u can sequence a series of cameras and then use LFO to animate between them.. Another technique is to use arcball camera, which is in the pallete. But for animating camera movements, camera blend is what I prefer.

hey i tried exporting stuff from blender with ply and after researching I'm almost sure that there are some complications with exporting ply and having the rgb color chanels does anybody know how to fix this? thanks in advance

about camera control: someone may have already mentioned it, but Noto the talking ball on youtube (im sure you know!) actually made a WASD camera component basically, there is a free version I use and its infinitely better than the default. They also have a video tut on how to use it, hope this helps :)

[on-necg]

excellent tutorial, you saved me with this, I just have a problem, I do not know if it is my object . ply, but I do not see the option of red, green, blue in the pointreference box, try with other objects on the internet and still do not appear the options

[theboytheycalljonny]

I went LFO > Math >Trail > dropped into the camera scale Z > worked out pretty well for me (generating IDM visuals) but I'm sure there's more refined ways :)

Thanks for the tutorial! I had a problem with the last step about the Texture 3D TOP, it shows "Error: Input 0 must 2D texture" starting from threshhold 1. I didn't have scaniverse so just used a random model, it took me a while to export it in ply(at first there was no texture showed), but still got this issue at last.

nice!
I think u can throw a null into camera "constrain to" as well as '''look at'', then do movement on the null

[andrearocca]

Hi!This work is fantastic.Thank you very much. I have a question. Can I switch between two differrent point clouds?

[emiliocasaburi]

Amazing video as always!! does anyone know why when dropping to select point file the red green blue parameters don't show up? I cannot use color information...

[dannyholmes]

Incredible Video! What would be the best way to export this? Every time I try exporting it as a movie, the video is completely black.

[严瑾-gp]

Does anyone know why the model doesn't rotate after I drag null to feedback?

[Skins]

Great tutorial. Really appreciate you for not gate keeping haha. Do you know how to make it interactive with hand movements either by kinect or just the camera ? I saw a video of a youtube video where the guy was using laser to build the fragments and it was connected with hand tracking.

[dotexe]

I did exactly what you done but my background does not turn black, it has a grew checkered pattern. Any idea how to fix this?
