There's a parameter on the toolkit comp to change the shortcut. You can also disable your graphics card's shortcut

You can change the shortcut with parameters on the toolkit comp or disable that shortcut for your gpu

@@tekt0 Okay thank you

Yes, you can do gradients using the fill color input with the SDF distance variable from the sampledPointMat. Reach out on either Instagram DM (@t3kt) or the #raytk channel on td-discord.com. I can put together an example

Interesting! Tell me more about how explosive promos are greater than star mapping!

Good question. That's the #1 most requested feature. Currently it isn't possible to convert vertex-based geometry (SOPs, obj, fbx, etc) into an SDF with RayTK. I'm working on some approaches that might work, but it's challenging. This page gets into some detail about the differences: github.com/t3kt/raytk/issues/657 It is possible to use render compositing to combine traditional rendering with RayTK but there wouldn't be any interaction between the two for things like shadows. This video covers that approach: kzfaq.info/get/bejne/e8uYqrejnayYiKc.html

Awesome! I look forward to seeing what you do with it!

Thanks! Feel free to reach out if you have questions or suggestions or whatever

Thanks! 😊 I'm curious to see what you do with it!

Might be extruding on the wrong axis which could block the camera. Check the extrude axis and try moving the camera around. Let me know if that doesn't work

@@tekt0 Yep, that was it! thank you for the reply and tutorial

There's a setting on the renderer "Show Background". If that is switched off, and there's a background field, it should do what you want.

It's probably connected to the wrong input. If you mouse over each input, it says what it's expecting.

thanks i will try =) @@tekt0

Thanks!

I'm not sure I understand the question. Is it about a specific part of the video?

@@tekt0 For example, the button module, TD's own module is to display "Button", but your module is above an oval wireframe, and then custom text. How does this work, please? thank you

​@@maming7286 There are a bunch of components in the TD palette under "UI / Basic Widgets". Those have lots of customization options including icons and text. kzfaq.info/sun/PLSqkC3f_BStxA4TpF6uWj3HOHPCglRpN9

Good question. There are some key differences in how SDFs are represented in Houdini vs RayTK. Houdini represents an SDF as a grid of points with distance values attached to them. RayTK represents an SDF as a mathematical formula that can calculate a distance for any point in space. In theory you could have a RayTK operator with a "formula" that's basically just looking up data in a grid produced by Houdini. That works as long as the renderer doesn't ever need to know about positions outside the grid. When using raymarching, the renderer checks points all the way from the camera out into the scene until it hits something. There might be a way to do it but I haven't gotten the grid approach working with raymarching. However, for volumetric rendering (pointMapRender) where the renderer is given a single position and does calculations for that, this approach can work. I've successfully done it with an early variant of RayTK that's used for an LED volume.

@@tekt0 Thanks for the quick replay. any link to the LED volume project? sound very interesting.

@@MenyAttenti it's still in construction and I think still under nda

@@tekt0 Thanks for the datail. :) but I mean, How do I open the raymarching_principle window at 0:50?

@@minjinlee899 Or if you mean how to access the viewer of that component: learn.derivative.ca/courses/100-fundamentals/lessons/101-navigating-the-environment/

So what you have set up is: sphereSdf (radius 0.2) --> moduloPolar (with default settings) --> raymarchRender3D (with lookAtCamera and pointLight)?

@@tekt0 yes I am doing exactly that but when I insert modulopolar the scene goes off, maybe my pc dont support modulopolar I don’t know

@@sunhalosonia There isn't anything in that operator that should be dependent on unusual GPU features. I assume you've tried changing settings on the moduloPolar? Maybe try another axis, change the offset, the pivot, etc. It won't do what this tutorial is aiming for but it would give us more information.

It works on both x and y axis, thank you!

@@sunhalosonia Maybe the camera is positioned somewhere that's intersecting with one of the spheres when it's using the Z axis. Make sure the camera is at 0,0,6. You can also try adjusting the rotation on the moduloPolar to see if that moves things so they aren't intersecting the camera.

You could use a speedGenerator to animate the Rotate parameter of the rotate4D. Select the rotate4D, ALT+SHIFT+R, animate with speed > Rotate. Then increase the value scale setting on the speedGenerator since angles are in degrees.

thanks!

😊

Really, it cannot be said enough. They are pushing the limits of this program and it's absolutely insane.

Interesting idea. I'll have to take a look at that. You can also use a field to generate the ids so it could vary using a variable or something. But for that you might need to use a render select to grab the raw object id output and do your own masking

Alt shift r

alt+shift+R

They should. What are you trying that isn't working?

@@tekt0 I sent you a message on Instagram with a picture of the error I’m running into. Just nothing happens when I plug the hex pattern into the 2d render but other 2d sdfs such as the star works for me

@@thattrippy9745 Hi, the error is because of the max resolution for non-commercial touchdesigner licences. The resolution of the 2D render may just be up to 1280x1280. By default it is 1920x1080. Thats not working.

@@aw_artwebanimation In the next release I'm gonna make it default to 1280x720 for non-commercial licenses
