TUTORIAL Race Track Builder - Inject elevation data and terrain texture

[Les Neilson]

For Oulton I should have something later today. I'll need to check what state it's in, and then I'll know pretty well how much time I still need to fill in the gaps.

 

[Les Neilson]

I have the lidar. It's 1m resolution, right? You got it from the same source, right?

 

[Pixelchaser]

yep , there is only one portal for the uk data right ? its 2 tiles a north and southern tile that I have merged.

 

[Les Neilson]

Okay, same here

 

[Les Neilson]

Out of interest, have you combined them into a geotiff, or some other format? I'm wondering if there's any possibility of loss of accuracy when merging

I don't think theres any loss. and I believe they are set up at their side to be merged etc. I think any error margin come from their adaptations.

 

[Les Neilson]

Officially back to work on Oulton Park. You wanted it subdivided to the max, right? Track surface plus border?

 

[Pixelchaser]

ehh yeah, might aswell, will just optimise it later I think. not sure tbh till I work on it, id work on the full lidar first anyway. good thing for this as a test is that having the lidar anyway can fix it if necessary

 

[Les Neilson]

Okay. It'll take a while, because the track is a lot wider than country roads in the dales

 

[Les Neilson]

I'll post a screenshot now and then so you can see how it looks

 

[Les Neilson]

Ignore the texture...

 

[Pixelchaser]

looks good Les.

 

[Les Neilson]

Starting to get a nasty crinkly effect

 

[Les Neilson]

Clearly I've reached the limit of the resolution of the data. Two options: I undo the last few steps and upload it so you can have a look, or I carry on the same way

 

[Pixelchaser]

yeah we don't want that if we can help it, undo undo

 

[Les Neilson]

Okay, the undo hasn't perfectly restored thing to the way they were. Have a look, if it's not useable I can redo it. We're still at the experimental stage. So, 1m resolution - stop subdividing at level 3

 

[Pixelchaser]

so how big is a tri at level 3 ? ideally I'm looking for 1 metre sizs tri`s, nothing smaller

 

[Les Neilson]

How wide is the track? 8-10m I think? If so, level 3 is probably a bit under a metre

 

[Pixelchaser]

well that's more than enough man

 

[Pixelchaser]

looks nice so far Les. just need to get into the nitty gritty of it. goin to hospital tomorrow so not sure how much ill get done over next two days but what ive layed down tonight seems too good to be true to be honest. but we find out soon.
