Setting brush options - 3ds max Freeform Modeling

Setting brush options - 3ds max Freeform Modeling Alright, so go back to the move tool, and hold down shift to break the tangent handles, and make a little, plateaued kind of landscape, and see what that does. I'll click and drag, and now I've got an interesting shape to the brush. Alright very cool, now there isn't really a good way to save what's in this window. I mean there's all sorts of interesting things like pressure sensitivity and the display options, but there's no way to really save this in a meaningful way. All we can do is just, play around with this and it'll be stored in the scene, and we can restore the curve back to the default S curve, with this button here. Alright, so I will close this, now there is a panel here labeled defaults that may or may not allow you to load and save the brush settings, I've had mixed results with this, so I'm not going to demonstrate it, but it's there if you're feeling lucky, and also as an aside there's a toolbar called the brush presets which has nothing to do with this and will also not allow you to save any presets.

Right, so I'll erase all of this by canceling it. Make my brush a little bit larger with control and shift, and actually give this, a real sculpt. Make this, something worthy of the tools, make the, brush smaller again with control and shift drag, and do another pass at details. Alright, so that's how we can edit the brush options and do our own custom brush shape, and in this case it's giving me a much more naturalistic feel to my landscape.

Setting paint options - 3ds max Freeform Modeling

Setting paint options - 3ds max Freeform Modeling Now regardless of the original state or the current state of the model, we're only going to be pulling those points vertically. So let's give that a shot. So I can paint here, maybe increase the offset a little bit, give it a little bit more distance per stroke, okay. And then exit out of push-pull. Go back into push-pull and paint some more. And we don't have the problem that we saw before. And that's because we're only moving the vertices in the Z-axis. We can continue to paint on here, and the surface will move up, but the surface will never self-intersect because we're only transforming in Z. And that's how to use paint options to prevent self-intersecting geometry.

3ds max Lighting Adjusting light shape

3ds max Lighting Adjusting light shape And we can change the exposure value again, set it back to a value of six, to see it there within that enclosure and then set the value of the exposure back to two in order to see the effect of lighting the room. And I'll just dolly back and position my view in the perspective view and we can see that it's still under lit, we need three fluorescent tubes in that enclosure, we can enclose in the top view and I can snap and just move this over by 15 centimeters exactly, right click on the 3D snaps or any one of the magnet icons. Make sure that you're snapping to grid points and in the options I want enable, access constraints enabled as well, those are the settings I want for the grid and snap settings. I want to snap in two point five dimensions, in other words I don't want to snap to the ground plane. Up on the main toolbar I can change the snap type, hold down the the 3D snaps button and switch it over to two point five D and then get in close enough in the top 

3ds max Lighting Adjusting light shape viewport so that you can see individual centimeters, hold down the shift key and move that object in x by 15 centimeters, you can monitor the value in the transform type in area at the bottom of the screen. Release the mouse, we want to create instances so that these lights will all share the same parameters. And I want two copies in addition to the original. Click OK, and now I've got three flourscent tubes in that enclosure and as we can see we're getting better lighting in our office. If you continue that process, making more instances, maybe with an array in order to populate all of the lighting fixtures with these fluorescent tube lights, that's how to set up the light dimensions using the shape parameters in a photometric light.

3ds max Lighting Adjusting light distribution

3ds max Lighting Adjusting light distribution Back up in the distribution types, the options that we have available here will depend upon which light shape we currently have chosen. So for a rectangle, I can choose any of these four options. The ones we've seen so far are the default uniform spherical, the current is uniform diffuse, the photometric web distribution type allows you to load in a manufacturer's lighting definition file. There's also a spotlight distribution. We'll take a look at that in the following movie. For a rectangle shape, once again, we should choose uniform diffuse. That's how to choose a light distribution type for a particular light shape.

3ds max Lighting Adjusting the Camera Exposure Control

3ds max Lighting Adjusting the Camera Exposure Control So to make that happen, I'll disable this check box here that says use physical camera controls if available. When that's on then you can set separate exposure for each camera. But that then invalidates what you do in here so that's very confusing. So I'm going to disable that. And now the changes that I make here in this roll out will effect all cameras, including the perspective view here. The exposure value is the sensitivity and it's default is six. Well I want it to be a bit more sensitive because of my light is not very intense. To increase the sensitivity, reduce the exposure value. And each whole number will reduce it by one F stop or will actually increase the amount of light reaching the sensor by a factor of two. So if I set the exposure value to five, then that doubles the amount of light reaching the sensor. Or four. Set it to a value of three and that's actually probably optimal for this scene with this material. If I bring it to a value of two, then we might get some over exposures here. 

3ds max Lighting Adjusting light intensity and color

3ds max Lighting Adjusting light intensity and color I don't tend to use the presets very much. In fact, I usually just type in the Kelvin value directly for the color temperature of that light. So I'll choose Kelvin, and it's defaulted 3,600 degrees and in fact, that's a pretty good value. I'm going to leave it at that. If you wanted to set a particular color for the light, not using it's color temperature, then you could use this filter color swatch here. I'll put the color back to it's default of D65 and then click on the filter color swatch and we can set any color we want here with just standard red, green, and blue values. Unfortunately these are eight bit values and we have range from zero to 255. All right, I'll cancel out of that, and that's how you set up the intensity and color for a photometric light.

3ds max Lighting Creating photometric lights

3ds max Lighting Creating photometric lights Right-click to exit object creation. Grab the move tool. Position it up so that it's actually floating above the floor. And we can enable lighting in our view port. Go to the view port label menu. And we have the shading menu which is labeled standard. Click on that. Go to lighting and shadows. Illuminate with scene lights. And if you also want to turn on shadows, you can do that. You can go back into that menu, which now says user defined. And go to lighting and shadows and enable shadows
