Hello I have been working through a character modelling course and have hit problems with weighting. The UV sets that I set up in 3D Coat become separate objects in the Cinema 4D hierarchy. You can see from the attached jpg that the legs are made up of sections from two different objects - the lower leg is part of the body and the upper leg is part of the cloth object (trouser leg in this case). After running the model though Mixamo I get a working animation. However when I adjust some of the weighting to improve distorting geometry, the two sections of leg break away from each other. I am working with R21 so don't have access to Delta Mush. What I have found resolves most issues is to unlock the joints that effect the area in question, make some Weight brush changes with auto normalise off and then smooth over in the Weight manager with auto normalise on. This technique does not smooth between the Cloth and the Body objects and so the leg break is hard to fix. Does anyone have any thoughts on this? And/or some suggestions for good online weighting tuition. I get the fact that every point has to have 100% weighting but I am struggling with some of the niceties of making adjustments with the Weight tool and Weight manager. Thanks in advance.

Thanks for the reply Igor. Sorry for the delayed response. I will upload a scene file in the morning.

Hello I am following a School of Motion course and using 3D Coat for UV unwrapping as suggested. I am experiencing a lot of issues - the main one being the presence of blue lines on the geometry which seem to indicate that the geometry will not unwrap as expected. I had thought that they were all due to overlapping points in the Cinema 4D geometry but a recent test has shown a model with blue lines all over it. I have tried the 3D Coat forum and was pointed to the Retopo room. I was told that the blue lines were sharp edges that could be removed. This doesn't appear to be the case however. Has anyone else experienced anything similar or/ and know of a solution? Many thanks.

That works a treat. Thank you.

Hi. Thanks for the response. Upping the luminance seems to make no difference.

Hello I am working on a scene that is lit by an image on a tv screen. I have added the image to the luminance channel of a material and it emits light into the scene when I select Global illumination. It is not very bright however. Does anyone know how I can increase the brightness of generate the same effect in another way? Cheers.

Thanks for the response Cerbera. I am not aware of what a "quad patch" is, so am a little confused as to how a particular uv island contains more than one. The islands becoming tiny and spreading out across the canvas (on occasion when I press 'unwrap') is an irritation rather than a deal breaker. Good to know about making sure that I equalise the islands when I get to that point. Thanks for that. How about the question of moving a seam? Once I have selected a seam and them unwrapped, am I stuck with a seam in that position? Or can I alter move it? Many thanks.

Hey. I am working with Cinema 4D 2023 and practicing UV unwrapping. I am coming across a couple of issues. Firstly when I try and rectangularize some UV islands, I get an error message "Invalid selection. Rectangualrize only works with one rectangular quad patch". I assume this relates to where my seams are but I can't find a way of moving them once they have been used to unwrap (become greyed out). I am also finding that on occasion, when I unwrap or fit canvas to UV, the UV islands are drastically reduced in size and spread out across the canvas Any tips to help with these two questions would be much appreciated. Thanks in advance.

Thanks for this.

Thanks for your responses Igor. ZRemesher is a good shout but I am keen to learn topology for myself. I think that there may be a way of raising the change of direction of the loops so that all the lower area can have a higher density of mesh without adding loops to the limbs or head.

Hello I have been retopologising a character using 3D Coat. The topology is shown here. I have managed to avoid triangles but the torso topology is creating alot of strange deformation when I upload the mesh to Mixamo. I realize that this is often a weighting issue but I have not been satisfied with the torso area and suspect that there is a much better solution for this. Any help would be much appreciated. JakS

Hello. I have been making good progress with Zbrush but regularly come unstuck with resolution issues. This is primarily when using the smooth brush but also using other brushes. I am aware that changing the size of a subtool can rectify this issue on occasion but I think this increases resolution rather than the reverse. The most recent example of this is when merging two subtools in a character sculpt, using Dynamesh to create a better topology and then looking to Clay Build Up and smooth to create the join that I want. Too often the smooth is too fine (even when I change the brush's settings) and makes the action nigh on impossible. Is there a way of reducing the resolution? Any good videos out there to explain these tools and issues? Thanks in advance. Jake

Thanks for the replies. The model is far from complete and I plan to retopologise. I will model the coat in C4D with a simulation as you suggest. Many thanks.

Hello am sculpting a character in Zbrush and imported where I am up to into Cinema 4D. I would like to pose the character into a seated position and need to remake the jacket so that it can distort to accommodate the new leg positions. I am keen that the simplistic cylindrical look is retained. Does anyone have a good suggestion that is achievable in Cinema 4D (rather than working with Marvellous Designer)? Many thanks. JakS

Many thanks Zeden.

Hello. I am experiencing issues when exporting a character from Zbrush into Cinema 4D. I am using Subtool Master and then Export in the ZPlugin drop down menu. I have the latest version of Zbrush and R21 Cinema 4D. The character appears without any colouring (it is shiny black) and some of the dynamic subdivision is missing. Any suggestions as to where I am going wrong? Many thanks.

Thanks very much for that Zeden. I will give it a go.

Hello all. I am a Zbrush beginner and struggling to get to grips with Polygroup selection and masking. I am following an online course and have created the cylindrical shape shown. It is divided into 3 polygroups. Mirroring is on so a similar inward extrusion is at the back. I have rectangular selection on, press Cntl and Shift and tap the inner green disc polygroup. This selects the green disc and hides everything else. The tutor is able to mask everything except the disc by clicking on it (keeping everything visible). Can anyone suggest how I do this? Many thanks. JakS

Many thanks Cerbera. Zeden- I will have a look at Wrap3D.

That's a great help Cerbera. Thank you. I will look into the HB modelling bundle. I have R21 so may not have some of the better tools. Cheers.

Hello. I have been working through a Zbrush video course which uses 3D Coat for retopology. I now realise that Cinema 4D is set up to retopologise a mesh. Is there any advantage in using 3D Coat over Cinema 4D? Many thanks. JakS

Hello all. I have been exploring techniques for facial motion capture for a project that I am working on. I have discovered that Blender appears to be offering a very attractive option using its motion tracking tools. I wondered if anyone had discovered whether Cinema 4D has an equivalent work flow? I am aware that Maxon now has Moves but have so far not been convinced by the quality of what it can achieve. Any thoughts would be very much appreciated. JakS

Thanks Igor

Many thanks Igor. I am pretty new to Zbrush. I have created a cube with Initialize. Is that how you created the block that you have shown? Cheers. Jake

Thanks Igor. Scene file attached. Scaling distortion.ZPR
