Hi, Most of my (blender) bezier roads on my map have HUGE (≈70% for some) slopes. So I'd like to make some signs with the slope indicated on them for everyone to be able to drive on them without having to get used to those (so far) ≈ 45 Km of asphalt and 25.6 Km of dirt "rally" road. I can estimate slopes trough any brush tool inside the terrain editor in-game (using max/min altitude indicated at the bottom right of the window and dividing by brush size, given that brush size is adequately chosen relatively to road width). But that's a gross estimate. Does anyone have a better idea ? Thanks !
You could measure from the gradient in blender? Since when you click on a node you can then find its xyz coordinates. From that you should be able to calculate the gradient of each slope. In fact, it would seem blender can do it for you... https://blender.stackexchange.com/q...en-edges-faces-or-change-the-angle-so-th/2334 You would need to apply your curve modifier before going into edit mode on the road (so that you can select the faces), so make sure to undo that or not save if you are not ready to commit to that.
Thanks for the answer aljowen, I thought of calculating slope through blender's bezier nodes coordinates. A bit fastidious and worse than the brush method for correctness because of curvature and the fact that node spacing is to large to find a maximum. As for the stackexchange forum link, that's making blender displaying face/edge angles versus the neighbouring face/edge. I would need the same thing but versus the horizontal/vertical. But I might just extrude a face next to the face I want the angle of and making the new one horizontal... And I'll copy my blend file anyway before turning my roads into mesh. You never know...
baking your road mesh to plane, it will give you normals values. Then you should be able to calculate the average angle of the slope. Still not practical solution :|
Add pitch UI app, drive car up the slope, put number you like best to sign? Usually steepest part is what is put to sign.
Thanks thomatoes50 and fufsgfen, Using normal went through my mind too but as you say, not practical. But I totally forgot the pitch UI app, which I never used yet. And that is as simple as it is appropriate !
Well : too much slopes, curves and combinations. I would spend weeks just measuring and creating/placing signs. I have simplified things : I warn but that's all. The curve signs do the rest.
