Houdini Tutorial - Lidar Data for UE5 Landscape. Part 1 - Heightmap 

Thank you so much!

Oh yeah! In all the years I didn't find the tool more convenient

double commander, same tool but free@@tinyredkite

@apetrukovich Thank you very much for the recommendation! I checked it out and it really is the same tool, so I decided to use it instead. Appreciate your comment very much!

Thank you very much! Appreciate your kind words!

A praise coming from you is especially valuable! Thank you for your words and for the knowledge you've shared!

I would never think of using HDA that way! Thank you very much for sharing!

yeah, it's something Indie Pixel did so I just ended up doing the same thing. It's much easier that way, if you reference the landscape material and name your layers it will also assign it and distribute them all@@tinyredkite

@@PeterLeban Awesome, I will definitely look into it. Thank you for sharing!

@@PeterLeban hi, can you add link for the video you mention, theres quite a few on that channel :)

@@andersmadsen8052 hm, can't find it online, maybe he removed it. I see other courses but not the one. But check Simon Verstraete's desert one for Unreal, same deal. Outputting landscape.

You are very welcome!

You are very welcome!

Thank you very much! The next parts are coming out soon.

Thank you for appreciating that!

Thank you very much!

I'm glad you liked it!

You are very welcome! I'm glad you found it useful!

@@tinyredkitelook forward to part 2. Also how did you decide on the area of the heightfield? Unreal recommends keeping world size within 20 km^2, I struggle trying to scale my heightfield appropriately to fit Unreal's limits

I'm not sure I understand your question correctly, but still will try to answer. I decided to use area 8000*8000 meters initially, because it encompasses the area of the world I was interested in. It could really be different size, as long as it's a square. Then I settled on using 4033*4033 landscape size (I think it was UNDINI who didn't recommend the biggest size). After that it was just a question of scaling. As I show in the video, the formula is as follows: 8000/4033*100 = 198. If my initial landscape was 6 kilometers in size, the scaling would be 6000/4033*100 = 149. If your landscape is super large, maybe you just need to split it into several landscapes. Please let me know if this answers your question.

@@tinyredkiteaaah gotcha. Makes sense

Awesome!

Are you referring to the nosy cat?

@@tinyredkite yeah, cute little helper 🐱

That's my fluffy, always ready to help!

Thank you very much, it's so nice to hear that! I was actually worried about my voice (and accent), but still decided to record the first video (which was very stressful). Now I feel more comfortable. Thank you for reassurance!

Thank you! Heightfield not being a square shouldnt be the issue. Could you please point the time in the tutorial at which you have the issue? There is more than one project node there.

Thank you for the tip, this was interesting to look into! I checked the documentation and a couple of videos and it looks very impressive. The only thing that is not so great - the maximum resolution of the tile is 512 pixels (according to Mapbox docs), which means that if I want 8x8 kilometers landscape at zoom level which will give me a resolution of 2 meters per pixel, I will still need to use 8 squares along each side. And the docs say: "You can join the output tiles of multiple Labs Mapbox SOPs together to form a larger piece of terrain", and then explains pretty much the same method I was using. But I definitely can see how this method can work for backgrounds, or extended, non accessible areas of the landscapes, where the resolution is not crucial at all, especially while it generates textures automatically! Also it looks like pretty much the whole world is available there, while not all the planet has the lidar data (I was using Tangram Heightmapper in such cases). As to the content in texturing - if you struggling to bring mapbox diffuse texture in Unreal - here are the steps you can try. 1. Make sure that your texture has the same size as your landscape (4033 or 8129 or whatever). 2. Inside of the landscape material editor create a LandscapeLayerCoords node and change mapping scale to the landscape size (4033 or 8129). 3. Plug the output of this node into UVs slot of the Texture Sample with the terrain texture. 3. Attach RGB output to the Base Color input. I will cover landscape layers and material setup inside Unreal in future videos.

Thankyou for this tip. I look forward to your future landscape materials setup videos as well.

You are welcome!

You are very welcome!

Thank you for the information!
