50<H2>Description</H2>
51<P>If the value of <SPAN class="argument">ev1</SPAN> or <SPAN class="argument">ev2</SPAN> is greater than 16, the alpha-blending coefficient that is actually set is 16.<BR><BR>This function uses the sub 2D Engine to change the brightness of the plane that was specified by <em><strong><CODE>plane1</CODE></strong></em>. If <em><strong><code>brightness</code></strong></em> is positive, the brightness increases; if it is negative, the brightness decreases. Furthermore, alpha-blending is performed on the translucent OBJ, bitmap OBJ, 3D screen, and the screen specified by <em><strong><code>plane2</code></strong></em>. Refer to the <CODE><A href="G2S_SetBlendAlpha.html">G2S_SetBlendAlpha</A></CODE> function for details on the <code>GXBlendPlaneMask</code> type.</P>
