Thanks for ur tutorials mate! Keep it up it's sick!

[@markus_knoedel]

Cool tutorial. Thank you.

Nice Video! :) And i got a suggestion: I made a similar video a while ago and functionstr pointed out, that working with TOPs is wayyy more efficient, since it works with the GPU (opposed to the CHOPS, that work with CPU).

[@reflekkt_net]

Thank you :-) Have to check out your video on this topic!
I honestly have a hard time working only in TOPs, as it doesn't have easy number values to work with. That whole pixelmath thing is not very conveniend to use for me... That black-white equals values between 0-1 is understandable, but how to work with it precisely is on another level :D For example I wouldn't know how to create values with TOPs like the speedCHOP does... Still a lot to learn for me :D
Working in CHOPs give me more performance tho than manipulating the grid with SOPs.

what exactly do you do around 6:12 ? i see you drop the pallette but then it cuts and all of a sudden it turns into a ramp

[@reflekkt_net]

Hi, you can go inside the dropped container from the ramp-palette-container and cut out the 'real' rampTOP. I don't know why it comes in a container when dropped from the component, as it's not so good to work with, but going inside, you will find the original rampTOP.

Hi, very nice video man, but I got a problem, I can see everything on the geometry viewer but when I export it i don't see anything and in the TOP viewer i can't also see anything, any idea of what can be wrong?

[@reflekkt_net]

Mhh sounds like your camera is positioned or pointed in the wrong direction. Try moving your camera manually with the transform parameters of the camera COMP, also check if its rotated in the wrong direction. In the tutorial the camera is positioned to 0, 0, 2 and rotated to 0, 0, and Z axis is animated with the expression absTime.seconds*10 .
Also check if your last nullTOP with the final output has the blue Display Flag on the bottom right turned on.
Let me know if its working for you.

Looks sick, but I have an issue after setting up the scale instancing. Once I set the scale channels everything disappears and only the black background is left... Any solution? Im a beginner

[@ole-petteralgard6208]

switched the ramp TOP to a circle and it worked..

i might be too new to attempt this, but I feel like you definitely go too fast, even at 0.75 speed i can barely follow where your mouse is going half the time.

Thanks for your feedback Jonathan! My tutorials need to be paused often to follow along. That way my videos can be shorter and the concept of the project is shown more clear, compared to "real time" and explaining every little step in detail, which might be too time consuming for many people.
But maybe I can find an even better balance between short cutting and getting into detail. Might do a Poll soon to ask what viewers prefer 🙂
