Hello! Sorry for the reply so late! I've been out the game stuff for a break. Thanks a lot!

Hello Dr.Sassi!

I'm building things for a game project. I found an error with a Boolean that I don't understand, as I have other segments of the same type, with no errors. Please take a look at this scene; I can't use booleans if I use slice to the object 02. However it worked in other objects like that, see 01
Thanks for your helpBooleanError.c4d

Hi Dr.Sassi! Thanks for your solution. Let me ask you; my original scene worked fine adapting to all curved walls. Will be possible to reduce the number of steps (clones) to half up to the cube added, without changing the angle, shape, etc ? Seems this option harder! Thanks again

Hi Dr.Sassi!
I have to make several stairs attached to circular walls of different diameters. Right now, I'm using radial clone & steps. I got the right Y angle but I'm lost to adjust the number of steps with this angle. I'd like to have the same Y orientation but just less steps. If I change the Steps effector, the Y angle changes. Seems a basic question but right now stuck! ThanksWallCircularStairs01.c4d

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!
