REALFLOW LEARNING EDITION HOW TO

I got the second glass, the one with triangular geometry made from a sphere mesh, to look like my first glass by changing a Convert SOP вЂњconvert toвЂќ prameter from polygon to mesh. It turns out that after more than a week of tinkering with it, today was the day I finally made progress on the project. You can still use the Real Flow Export SOP though вЂ¦ Wonder why that is? Anyone know? I know Maya won't let *any* plugin be loaded in their Personal Learnig Edition вЂ¦ now, we don't wanna be like them do we вЂ¦ ? Gotta run, let me know if you have any problems with the RF stuff. I also just realized that the Apprentice edition won't let you execute the Real Flow SD File ROP for some reason. (The Linux version doesn't have these yet). The output formatting needs some work, but it can help you debug the problem too. Also, in the current Real Flow demo file on my web site you'll find 3 small utilities that will dump the contents of Real Flow particle, mesh and SD files. Check the spreadsheets, write out files, scope channels, whatever it takes, because it's not always obvious. The reasons for this are beyond the scope of this conversation and unfortunately leads to a lot of wasted time, frustrated operators, irritated managers вЂ¦ The best thing to do when you're not sure, is to make sure. For whatever reason, there are numerous вЂњplacesвЂќ and вЂњstatesвЂќ in Houdini which can lead you to believe something (like I've converted the geo correctly) and it's not true. geo file, then examine it for correctness.

As you mentioned, following the operation with a Convert SOP, set to polygons and triangles will not *always* convert everything to triangles вЂ¦ The only way I know how to check is to write the geometry out to a. trying to convert the result of the Boolean operation into triangular polygon data. Yes, the Boolean works (pretty much) as advertised, but there's some black magic that creeps in every now and then вЂ¦ e.g. I've have many problems over the years with the way geometry gets built in Houdini, one example is what you're dealing with right now. hip file and found a few problems, not many of which you can solve easily unfortunately. Second question how do I make a Cookie SOP union act like a Boolean SOP union? Hi Mike, I'm not sure why the shader is behaving differently on what seems to be similar geometry. I made my second glass out of a sphere mesh, moving the points around until I got the right shape. Mikela вЂ¦ I made my first glass with two capped tubes and a Cookie SOP, hoping to simply use the convert SOP to convert to triangular geometry, but the geometry would not convert.

The Cookie SOP is sensitive to surface normals, which I suppose is how it's able to deal with open surfaces, but then I need a way to filter out the parts of the mesh with the wrong normals. So I suppose one solution is to close the geometry and use the Boolean SOPвЂ¦but I don't know how. hipnc file is here Second question: how do I make a Cookie SOP union act like a Boolean SOP union? The Boolean SOP cuts holes in the geometry just the way I want, but won't work if the surfaces are not closed (as some of the RealFlow meshes are not). But while I now have triangular geometry, the second glass won't refract light naturally like the first (or even reflect the same in OpenGL), and I don't have a clue why it won't.

I made my first glass with two capped tubes and a Cookie SOP, hoping to simply use the convert SOP to convert to triangular geometry, but the geometry would not convert.

I've had no problems importing particles or meshes, but I have had a few unrelated problems due to my lack of experience with Houdini: Making a glass with triangular geometry (necessary for RealFlow import)and the correct refraction characteristics. I've been playing with the RealFlow ROP/IFD plugin (thanks, Mark!) and wanted to put a tweaked version of the Real Flow вЂњ2 FluidsвЂќ example into Houdini as an excercise.
