Why Does Lightwave 4.0 Crash When Attempting To Change Animation Type? |
|
Answer» There is a known bug in LW 4.0's HANDLING of the scene FILE parameter for the animation type. The workaround is to edit the scene file in a TEXT editor. Look for the line: AnimationType 4 (the number will vary depending on what you selected for type) and either remove the line or change the number to 0. Another workaround is never to save the scene with an animation type selected; always wait and select that at RENDER time. This is fixed in LightWave 3D v.5.0.

Why Does The Pointer Disappear While Using A Diamond Stealth Card? |
|
Answer» Toggle NUM lock a few TIMES, you should get the pointer BACK. Weird but it works. We're using Stealth 64 DRAM version here on a couple of machines. If you don't have 2MB on the card, add RAM, and if you don't have the drivers that will let you do 64K colors in 1MB and 24-bit color in 2MB RAM, you can download them from the Diamond BBS, they were recently POSTED there. Check your manual for the number. Toggle num lock a few times, you should get the pointer back. Weird but it works. We're using Stealth 64 DRAM version here on a couple of machines.

Common Lightwave Problems With The Mac Platform? |
|
Answer» If you are only familiar with the Mac platform you will notice two problems that may cause LightWave to crash. Firstly LightWave as yet does not come with much in the way of error trapping which means that LightWave can EASILY crash your Mac if something goes WRONG. A good example of this is that normally on a Mac Application you can be two or three moves ahead with keyboard commands, the Mac will catch you up and PERFORM them, but in LightWave using the keyboard faster than the application can cause the Mac to crash. Secondly LightWave does not have any onscreen progress notification (eg : a clock or a progress bar). If LightWave appears to FREEZE just after you perform a task, it is performing the task. A freeze is INDICATED by the user not being able to move the mouse on screen. If you are only familiar with the Mac platform you will notice two problems that may cause LightWave to crash.

Can I Use Two Monitors On A Graphics Card With One Svga And One Dvi Port? |
|
Answer» Yes, so long as the card is actually designed to do so. Some cards with an SVGA connector and a DVI connector are designed only to send the same display out both ports. Other boards use a DIGITAL-only DVI port (DVI-D) that cannot be adapted to an ANALOG monitor. The card must have a DVI-I connector that provides both analog and digital signals, and must be a true dual head card. Some such cards, the Asus V7100 2V1D for EXAMPLE, INCLUDE a DVI-to-SVGA adapter. You can also purchase such adapters. Below is a list of sources. We'll be adding sources of such adapters to the list as we locate them. Yes, so long as the card is actually designed to do so.
