I'm using now the Loft with several curves in a separate piece on top. I think I can manage. Thanks anyway for your help! By the way, there are too many modelling tutorials. Any suggestions? Javier

Hi! I was trying with the Helix and found now a better way! Last night couldn't! See attached. Now trying to adjust the start & end openings.Maybe is better to use your option. Thanks!

Hi Dr.Sassi!
Thanks for the scene! Got one question; see the scene that fit's what I'm looking for enclosed. How can I make the loft be equal top to bottom? If you see the cubes added, the top is wider than the bottom.

Hello Dr.Sassi!
I'm trying to model a slider. See the scene enclosed. Right now the bottom is narrower than the top. And I'd like to add a curved start so it connects with the square more or less. The slider will be below a square hole in the floor (the square line). Appreciate your help!
Thanks!

Hi! This one looks fine in Unreal! I think need to learn well the alignment of UVs after modelling with booleans. I'll watch the tutorial. Thanks!

Hello! I'm modelling in C4D but the project is a game (kind of Riven) in Unreal.So texturing and everything else is there. By the way, how easy will be to make games in C4D. Wish Maxon expand into game engine! The tutorial looks good! Thanks a lot!

Hello!

I made an object, that is part of a large structure, using booleans. Textures are not aligned correctly due multiple cuts with booleans, I guess. Is there an option to convert the object to show textures as a cube? I mean all aligned? See scene. Thanks

Hi Dr.Sassi! Now I understand the process! Thanks so much!

Dear Dr.Sassi, Is there any tutorial with this part you describe? I can't replicate it. Besides, can't send you pictures. Thanks

Hello!

Both models work! How did you fill the wall in the bottom with a polygon? If I use Close polygon, it makes a single polygon the whole bottom. I need just the thickness of the wall.

Hi!
I did an object with splines, extrude and thicken. In C4D looks right but inside Unreal Engine has no thickness, just flat. See the originalExitBasementStairs01.c4d

The other one seemed too complex for me! Thanks a lot! That's done with it!

Hello! I see two problems in this solution; I'd like to make the handrail one single piece, like made of concrete. And I need to make another group of stairs shorter in the same cylinder. Besides I see many elements! So, is there no good option to make it simple, like the first sample I enclosed with helix & sweep? Thanks again!

Hello! I have another question related to the stairs. How can I make a curved, spline, handrail that goes from the top to the bottom? I'm having problems to get the exact shape of the stairs. See scene. Thanks!

Perfect! Thanks a lot!

The curved version has several stairs. How can I make it a single one?

Adapted to the curved wall

Hello! Both are fine! But inside the cylinder.
