Trying to figure out what this effect is

2012-05-04T15:13:51+02:00

In this youtube video, someone clones a model, moves it to the left, then does something to make the clone appear more smooth and round. I'm just now learning softimage and would like to know what this effect is. I can't find information on it anywhere. The guy uses it around 0:36. link: http://www.youtube.com/watch?v=oW8PIF7Yvkk

Duplicating or instanciate along a path or curve

2012-04-25T13:00:16+02:00

Hello all! I am trying to find a way to duplicate or instantiate a model over a path or curve, more specifically a rope! You can find an image of the model here... http://www.mediafire.com/imageview.php?quickkey=rvtau4zlzll8m9w&thumb=6 I have found information on doing this in Max and Blender, but cannot find anything usable for Softimage. The idea is to duplicate or instantiate along curve or path and have the different pieces merge with each other! Any pointers would be greatly appreciated. Gilles

Parametric Formula Plugin

2012-04-04T19:48:11+02:00

With this thread, I will explain the Parametric Formula plugin. [b]Motivation.[/b] I design the plugin to fill a need for generating shapes using parametric equations found over the internet. The plugin was as much an experiment with NURBS as it was with math formula. [b]Installation[/b] Download the plugin here at the Area Download section. The plugin is called, of course, Parametric Formula. The plugin was coded using Softimage 7.01 so it should work with this version up. I have not tested the script with earlier version. Decompress the file and Install it in your plugin directory of Softimage. This is a self-install plugin, it should be detected by Softimage on startup. If not, use the plugin manager to load the plugin. You will found the plugin in your primitive selection menu. [b]Math functions[/b] When the UI open up, you will notice the default setting of the sphere primitive. The plugin is coded in JScript and most math.functions have been implemented within. You will notice that formulas don't have the math prefix. That is because the plugin is coded to accept both version such as math.cos(n) or just plain cos(n). Also coded are new math functions such as cosh, sign, ln and several others. In my next post, I will provide tables of these math functions and parameters. [b]Limitations[/b] This plugin is slow. On my low spec machine (AMD 4400 X4 Dual core), I generate complex NURBS in approximately three to four seconds with subdivisions set at 100 for both u and v. I have limited the u and v subdiv to a maximum of 1000 (that is 1,000,000 Control points evaluated on 14 formulas/subformulas). If you want to stess test your machine, go ahead, but don't blame Softimage or your computer if they go on strike or worst, stand up and walk off your desk in protest. The plugin does not include a complex number function. So if you provide formula that generate complex number such as sqrt(-1), you will not see a nurbs surface on screen or in the quick render. Some formulas can be made to remain within the real domain by restricting the u min, u max, v min and v max. Check the kiss surface preset for an example where v max was restricted to less than 1 to prevent the formula to calculate imaginary numbers. The plugin create one Nurbs surface. If you need to generate multiple surfaces, you will have to generate the object in piecemeal or, if you are a programmer, modify the code to feed the nurbs count of AddNurbsSurfaceMesh2. Be aware that the plugin will create self-intersecting surfaces, non-manifold and internal control points, edge and polys. Softimage and Mental Ray will throw warning during render, but so far, it has provided good render for me. Your render will show a nasty seam, that it because I have coded the surface to overlap control points in order to close the surface. You can avoid the seam if you generate the surface with linear degree, or use the nurbs to mesh to convert it to poly (work sometime). [b]Presets[/b] I have provided approximately 121 presets with the plugin, open them up and check them all to see how to enter formulas and generate nurbs and meshes. Don't forget to lock the UI if you want to experiment. Start with the plane and simple formulas like the saddle. Because you are working with Nurbs, you will notice the x, y, z, and w in the interface. The w parameter control the weight influence of that control point on the nurbs surface. In most cases you will leave the value to it's default of 1. One preset for the sphere has an example where I fed the w with a sine function. The result was a slicing of the sphere. The w is an interesting twist in generating parametric equations. So have fun with NURBS, mathematics and parametric formulas in Softimage! Cheers! Dan

Smoothing trouble

2012-03-21T16:27:21+02:00

Hi everyone. What I want to do is export a smoothed high poly mesh into zbrush and then reconstruct subdivisions in zbrush. I have hard edges and vertices marked, so when I use the plus key to subdivide it works how I want it to (like smoothing groups would). However, when I export after subdividing with the plus key zbrush doesn't notice the smoothing or the subdivisions. Since marking hard edges doesn't work anywhere but Softimage, how do I get the same result as subdividing with the plus key when exporting?

Shifting Grid Topology Keys - Interactive Samplers

How to deform areas of a character mesh according to the strength of its grayscale texture map?

2012-01-03T23:35:49+02:00

Hi all, I'm picking up Softimage after a hiatus of quite a few years so that makes me a n00b to this forum, but hopefully I'll get to contribute more as I pick it up again! I was wondering if any of you, have any thoughts or ideas on how to solve a problem I'm stuck on: Using a single, template character mesh I'm going to unwrap a grayscale texture map. The real challenge I'm trying to solve is how to deform areas of the character mesh, based on the strength of its grayscale texture map? That is, if you paint the texture map's belly and thighs dark black, then the mesh will deform to look like a fat man and if you paint the texture map's forearms and chest dark, the mesh will look like a body builder. Is there any existing tools to enable this with enveloping or ICE? Or does anyone have any ideas on how to create this? The solution has to use the grayscale texture map as a basis for deformations. Any help would really help get me started as I've been stuck on the solution for a while. Thanks a lot!

auto assign multiple textures to deck of cards ..

2011-11-22T04:41:25+02:00

wondering if anyone has created a script or better still TOPO ICED a way to connect many different textures-> 2000 in all to 2000 different meshes ( they are copies of one)

Tips for reducing polygon count

2011-09-20T08:05:52+02:00

Hi, I've recently started playing around with 3d design, so I'm pretty green with 3d modelling. I've been trying to take apart royalty free models and test certain techniques on them. One of the things that I would like to know how to do is take an existing model and reduce the polygon count (to make it more game friendly for instance). Is there a tool/technique to do this in SoftImage, or is the only way to simply delete polygons and replace them with approximations? I should mention that I have seen the poly mesh -> polygon reduction option. I'm wondering if that's considered the best option, or if there are some user tricks beyond that option (or perhaps tricks to using that option). Thank you for any help.

shell / solidify

2011-08-27T13:06:58+02:00

Hello some time ago i found a Solidify modifier addon for XSI, that was the same as the shell modifier in 3ds max, i cant find it anymore, anyone has it please ? <.< Where it can be downloaded ? i dont remember.. Thanks :) In the NETVIEW link doesnt work, it let you download or install the scatter vbs, its not solidify. The movenormal is an alternative, and the kim-aldis is an alternative too <.< Still the one i found was totally the same as 3ds max, but i cant find it anymore
